A short, charming puzzle-VN with a good story and voice acting, but simple gameplay.
Players praise the game's mix of visual novel and puzzle elements, with many noting the story and voice acting as highlights. The characters are described as charming and the music as catchy. [2][5][7][16][20]
However, many criticize the game's short length (around 1-2 hours) and simplistic gameplay, which some find too easy or glitchy. The story is also called predictable by some. [9][18][32][34][35]

60 of 191 · most liked firstThis short kinetic visual novel feature an anonymous male protagonist referred to as The Unhacker. As the best unhacker of Smash Security, the Unhacker attempts to investigate the source of the 5K Worm virus infection that is spreading across cyberspace with some help from his AI companions Weedy and Miss Debug. Suspecting their immediate competitor ACME Antivirus to be behind the creation and spread of the virus for financial gain and profit, the Unhacker attempts to hack across multiple…
positive · reviewer's own thumbsView post →Unhack is an indie puzzle game with a story that is delivered in visual novel style. For a rather decent price, you'll get a hour or two of very nice story, well made backround music with anime styled sprites dubbed by english voice actors. I will try to avoid all spoilers in these few words I'd like to share about my impressions. First of all, for such a short game, the story is very nice. It has everything from a nice start to a well done climax. The characters are nice. To my suprise even…
positive · reviewer's own thumbsView post →Unhack is a bizarre game. It's a mix between a visual novel and a puzzle game where you go from point A to point B. Unhack, story is pretty bizarre as well. You play as the unhacker and you have to go through data streams to stop the 5K worm. The gameplay is you moving a square through orbs, but you can only place your square on the orbs. There are viruses and lasers that will destroy you on impact. There are boss battles where you have to shoot at the AI core to destroy them. The visual…
positive · reviewer's own thumbsView post →Unhack (2014) is the sort of pleasant surprise you’d never pick out from a glance at its simple artwork, seemingly basic mechanics, and emoticon laden dialogue. Rest assured Unhack isn’t complex, nor does its artwork ever emerge as much more than it first appears, but the game is carried by an infectious charm and a recognition by its developer of their limitations (which are then subverted by played as a strength). By the end I was rather taken aback just how much I had enjoyed myself.…
positive · reviewer's own thumbsView post →An enjoyable merger of puzzle game with a visual novel style storytelling. It's fully voiced too and the actors do a solid job for such a small project. Certainly worth a look if you like puzzle games
positive · reviewer's own thumbsView post →I really liked the basic idea of the gameplay, but it was much too easy. New gameplay mechanics were introduced in each chapter, but none of them were fully explored. The timing sequences didn't really get any harder from the beginning of the game onwards. My suggestion would be to add in some puzzling elements to spice it up and make the game longer. The playtime is definitely too short (about 40 minutes to beat once) when compared to the price. Art was fine. It wasn't spectacular, but…
negative · reviewer's own thumbsView post →Awesome mix of visual novel and simple puzzle game, with very nice graphics and sound and a wide range of difficulty levels to choose and memorable characters, this game is very fun and it is not a 10/10 only for the reasons stated below: - your own character has no voice and that makes you have to go back to a previous line of a conversation, as characters speak while you play; - there is no way to know where you are in the story, unless you memorize the last chapter you played; - no…
positive · reviewer's own thumbsView post →Played it for story :D Well, there is nothing else to play this for, but that's a good thing. Characters are charming, puzzle / action part is rather easy and don't expect Sakura Spirit here, so story is all what's left. So, it's not best story I ever seen, but it surely kept me interested. It gets from intentionally funny to downward ridiculous (I mean, you are removing viruses by firing a canon!), but it surely has its nice moments and it's perfectly worth those 4€ that dev is asking for.…
positive · reviewer's own thumbsView post →This is a game you truly play mostly for the plot, the gameplay itself is very simple, move around in simple while avoiding obstacles and unlocking the paths to the next area. Upping the difficulty makes this game a bit more challenging if you're into that, but honestly this game is a tearjerker by the end (Without spoiling anything!) Don't let the simplicity of this game fool you, it's a great story that progresses as you're playing the game and moving around each area. Despite all this, I do…
positive · reviewer's own thumbsView post →Unhack is a mix of visual novel and light puzzling. Short and sweet at a little over an hour with infinite lives at normal difficulty. It started negatively for me with the usual "pervert" main character, but I ended up liking the story by the end. Amateurish fan art but not terrible. The "unhacking" mini-game with extremely simplistic graphics was more varied and interesting than I initially thought. It did require a bit of reflexes by moments so it wasn't pure cerebral puzzling. Unhack was…
negative · reviewer's own thumbsView post →Unhack is a game that I recommend because: - it has a good price - it has a decent story - it is a good visual novel - it is short - it is atmospheric - the graphics are good - it is relaxing - it has an interesting concept - it has trading cards Enjoy!
positive · reviewer's own thumbsView post →Whelp, I guess that was all of Unhack. At a full 61 minutes of playtime, do not mistake this for a long game. Should you get it though? Eh, why not. Gameplay consists of guiding a small orange cube through top-down levels representing the insides of computer programs. You travel by means of nodes, so there's no real exploration element, it has more of a puzzle vibe to it. On its own this would be boring, you're playing this for the story. The story is that of an unhacker (...the term is never…
positive · reviewer's own thumbsView post →Unhack Destruction is an interesting mix of VN + Puzzle/Strategy/Action game. Regardless of the devs inexperience when putting this title together, as they state it was their first one on steam, the game flows pretty well and isn't too long or drawn out. Some games you feel they could have just stopped and you would have been happy, or they continue to make insane challenge after insane challenge. That's not the case with Unhack. It feels just about the right length for the type of game that…
positive · reviewer's own thumbsView post →A nice little game that crosses the puzzle and visual novel genres. Solid art, voice acting, interface and gameplay. The only detail to critique is the lack of a resolutions option of some kind, the game is locked at 4:3. The game can be finished in around 1 or 2 hours but the story is well told and communicates the message without problem. There is some replayability but is more of a one time experience. A solid recommendation.
positive · reviewer's own thumbsView post →MORE PEOPLE SHOULD PLAY THIS The game is short but really enjoyable, its a visual novel/puzzle game that lasts about 1 1/2 hours but it's a extreamely cheap game so its expected. The game is worth your time, I can tell you it was definetly worth mine. Pros. > Simple but fun gameplay. > Mostly good character design. > Cheap. > Funny at times. > End cards. > Good characters. > Forever Denied (You will get it when you play it.) > Good voiceacting: #Xanthe Huynh - Ui Hirasawa from K-ON! - Sachi…
positive · reviewer's own thumbsView post →Pretty simple action/puzzle game with an overly dramatic storyline that's over in an hour or two. Can't recommend it at full price but a sale or bundle, sure, it's decent for a brief distraction.
positive · reviewer's own thumbsView post →Remember there is a free demo that covers 40% of the game. If you are interested, just play that first. In any event, this game just... underwhelms. It's basically a visual novel with some basic gameplay thrown in to appease those people who claim that simply reading text "isn't a game", but the problem is that all it does is create a minor obstacle course to slow the player down in between text segments. Since all you do is use the arrow keys, it basically amounts to being told to push the…
negative · reviewer's own thumbsView post →Gameplay: 4/5 Visuals (inc characters) 5/5 I really enjoyed this game, the objective is to destroy the "5k Worms" across 10 stages along with Weedy and Miss Debug, the characters are fully voiced and the artwork is excellent! That, I was impressed with, Miss debugs *Yawnies* were cute too. heh... The only things I would improve is fixing the Steam overlay in-game (it doesn't allow/work) and the puzzles/stages could've been more challenging (but I did play on easy afterall) Deffinately worth…
positive · reviewer's own thumbsView post →Very simple gameplay, though it's fast and flows fairly well. The art is adequate, nothing remarkable. Unfortunately, the gameplay is glitchy, the completely stock storyline barely registers a pulse in its brief run, the characters are equally one-note, and the voice actors seem like half the time they're not even completely sure what their lines were supposed to mean, with unnatural tonal fluctuations and complete emotional stiffness. The aforementioned acting is possibly the game's most…
negative · reviewer's own thumbsView post →Very short and the gameplay is rather simple, but the story & characters are very good and the voice acting is excellent, so this game has the recommendation.
positive · reviewer's own thumbsView post →This game is super-short and if you play on "easy" it is just basically a walkthrough of the dialogue. The story is a little preachy and predictable, but the voice acting is decent enough. I do recommend this title as a fun little visual novel piece, but it really isn't even worth the $4 price tag. It's probably best to find it in a bundle or on a deep discounted sale.
positive · reviewer's own thumbsView post →This is a simple game. It's nothing spectacular but a fun puzzle game. It doens't take long to pick it up and the difficulties seem just right. You play as someone named 'Unhacker', delving into cyberspace to stop the 5K worm from expanding. The game is, well, simple: move your box, which Unhacker is controlling, to solve puzzles in cyberspace, the whole time trying to stpo this virus.The game is fairly short but, for the price of about 4 dollars, not even on sale, it's perfectly fine. There…
positive · reviewer's own thumbsView post →Unhack is a choiceless visual novel that includes a timing movement minigame. Go for it if you like manga girls that are expertly voiced and enjoy talking to AIs. I liked the dynamics between the AIs themselves and the player. The playthrough took me 75 minutes on unlimited health, but I tend to skip the ends of the voiceovers.
positive · reviewer's own thumbsView post →The story is more dramatic than I expected (plus I like an AI-themed visual novel). The music are pretty catchy. The puzzles are okay. The issues I've found so far in this game are: - No saving system. You have to memorize the chapter you left off by yourself. But it's not a big issue here because the gameplay is pretty short (about one and half hour to finish the game). - No windowed mode in this game. (I heard that it's about the game engine so nothing could be done about that...) - The game…
positive · reviewer's own thumbsView post →Decent story, simple relaxing puzzles, and for a cheap game it's really nice to have it narrated and not just have to read everything; wish more indie games used voice acting instead of making a game feel like a book. It is rather short, but for $4 its not bad.
positive · reviewer's own thumbsView post →Unhack is by no means a groundbreaking gaming experience. There are a few technical issues that may hamper your experience. The game will last under two hours, all told. All those gripes aired though, I can say I did find the game moderately enjoyable. The gameplay of Unhack somewhat reminds me of Chip's Challenge, though much simpler, with more of a focus on action than puzzle-solving. There's nothing particularly interesting or challenging about it and it serves mostly as way to pass the…
positive · reviewer's own thumbsView post →Unhack is a short little puzzlegame that can be quite tricky at stages. The main goal is to move your block to the goal, some goals are simple "get there" stages, some are bossfight stages where you have to repeat a more or less simple (but still harder) mechanic 3-4 times in a row. The puzzles at its own would be not that awesome, but they pack it in an quite tempting story where you take the role of an "pervy" [wants to try out his costume mods on the AIs, he gets "forever declined"]…
positive · reviewer's own thumbsView post →I enjoyed this game. though the game may not be anything fancy in terms of art style or game play both of which are not bad as i still enjoyed both, i think the story was what truely made this game shine, by the end of it i felt a little upset of how it ended and that this was the end, i wanted to play more even ;p when a game can do that to you, you know its a keeper ;p the playtime on the game is roughly around 2 hours and if your like i am it will leave you wanting more ;p (not a bad thing)…
positive · reviewer's own thumbsView post →A very nice game. Puzzle mechanics is simple enough - but quite challenging, if you choose a higher difficulty level (without unlimited lives). And the story is interesting to follow. Parts of it are funny, parts - sad, and all together - very human. And I demand the costume mod! :D
positive · reviewer's own thumbsView post →This game has it's moments and dialogue throughout the story that has made it enjoyable. In my opinion, you have made a game easy and enjoyable. That is hard for some. As well as it has an increased difficulty, the cg in here is good and steam will not allow screenshots. Wonderful artwork, good short storyline, levels are timing, and the dialogues on the way are amusing. I still stand by "I want to see that costume mode". The only other thing I wish was installed was a cg viewer if you beat the…
positive · reviewer's own thumbsView post →A short but fun puzzle VN.
positive · reviewer's own thumbsView post →Unhack is in its core a pretty good Puzzle Game with 10 "Maps". The entire game took me pretty much exactly an hour to complete, however I also did it on the easiest mode, where you can as many times as you want. Normally I am not really a Puzzle Game kind of Guy, but I honestly enjoyed it here. The Mixture between the Puzzle and the Visual Novel Aspect really fit and although the Story isnt anyhting super exciting, I found it to be pretty cute and likeable. What I also liked was the English…
positive · reviewer's own thumbsView post →Fun puzzle game that's not too difficult to pick up, the characters are great, the "AI" are voice acted which is a nice plus and a nice story to pull you in. To be honest, full price may be a bit too much for this game, but when it's on sale and you can spare two dollars or so, go for it. The story is actually quite well done for a game that is so short. The "AI" all have their own unique "quirk" to say; as one constantly has to remind you that IT'S A SMALL 2, GET IT RIGHT! I'll try not to…
positive · reviewer's own thumbsView post →Short little puzzle game, kinda cute. The main char is an unlikable creep but the little deviant art girls are friendly and the game is worth running through for a dollar. Don't expect something too deep and just enjoy whats there.
positive · reviewer's own thumbsView post →Short, but satisfying. The puzzles are challenging enough to make you think, but not to the point of frustration. The characters were fun, and the voice acting captured their personalities well. The story kept me glued to my keyboard. All in all, a good game. I look forward to seeing more from this team.
positive · reviewer's own thumbsView post →Unhack (2014) Anime style game where the story is told as you play in real time. You hack the system by navigating your way through the system, dodging worms and other nasty stuff as you make your way to destroy the virus at the end of the level. Not your average visual novel game but still great fun non the less. 7/10
positive · reviewer's own thumbsView post →Unhack is a rather poor puzzle game mixed with some extremely bad visual novel elements. I can't really think of anything positive to say about this one. The puzzles are extremely simple and easy, the story and the voice acting are atrocious and the game doesn't even support any widescreen resolutions. Avoid! The good: - Nothing The bad: - Lackluster gameplay - Terrible story - Poor voice-acting - No widescreen support
negative · reviewer's own thumbsView post →On one hand, it's a fairly easy but amusing action puzzle game, at least if you're not playing on Insane. I don't think it really ever puzzled me except during the very last mission, so much as it required me to time doing the obvious thing properly, but eh, I still had enough fun with it. It also has some decent voice acting, though I didn't particularly like Weedy's voice as much as the others, which is awkward since she's more or less the main voiced character. On the other, the entire game…
negative · reviewer's own thumbsView post →This is the most dramatic puzzle game you will ever play. the game isnt too long, you can finish it in less then one hour. Its based around AI and their melancholy. Oddly enough there is voice acting which i wasnt expecting furthermore i wasnt expecting it to be good voice acting. Its a great little pass time if you have time to kill.
positive · reviewer's own thumbsView post →Fun and engaging plot with some interesting characters and a nice twist. The voices also add a nice touch. Thumbs up :)
positive · reviewer's own thumbsView post →This Game is different i have played many vns but you can see the amount of effort put into this as you open the game the amount of work and the game is acually very enjoyable if you give it a chance. I think if you enjoy vns you will enjoy this also. P.S. its not so much of a vn it has vn elements but its more of a stratagy game which i like. And the voicing is acually pretty good.
positive · reviewer's own thumbsView post →Everything feels extremely cheap, uninteresting, cringey, unnerving or a combination of two or more of those. It has some little charm, but it's not enough to make it a positive experience :/
negative · reviewer's own thumbsView post →An instatnat classic, Makes me think of Megaman NT warrior, with a touch of Vocaloid. It knows what it is and who it caters to; A light novel puzzel game that doesn't take it's self too seriously as it appeals to computer science Otaku with a thing for AI Waifus. To explain why I love this game, I think can be best summed up as; 'It's a case study in minimalism- how to do it well without sacrificeing depth.' The puzzle elements are easy to grasp yet the nuance of skil isn't lost, The story and…
positive · reviewer's own thumbsView post →Alright Unhack, we need to talk. I like puzzle games. I like visual novels too. I think we both like both of these things. So why on earth did you take the most boring tropish components of each and mashed them together? No, no, I don't hate you. You're a good kid and I know you mean well (your art is nice for what it is), but it felt like you made this game with cruise control turned on. Now I know you have a lot of dlc and a sequel, but I have never played an easier puzzler, nor gagged harder…
negative · reviewer's own thumbsView post →A rather very short game with super easy puzzles/actions and a pretty good story. I enjoyed it but would recommend buying the game in a bundle or when it's on discount.
positive · reviewer's own thumbsView post →Don't get me wrong, the game was alright, the story was ok & the ending was alright though predictable. However, the tag for the game was visual novel & puzzle, the game didn't feel like a puzzle game. It was more of a wait and react type of game with obvious solutions, like in "The Impossible Game."
negative · reviewer's own thumbsView post →In short, it's sort of a maze with some obstacles you'd have to pass through.. and there's a story told in between, in a japanese visual-novel format. All in all it was mediocre.
negative · reviewer's own thumbsView post →What an entertaining way to mix up a visual novel and a puzzle compilation! The art and voices are charming, the music is pretty good, the dialogues are well-written, the plot is twisty and touching; the puzzles, however, aren't at least just a little as smart and brain-breaking as in my favourite hacker game, Exploit. But as a whole it brings this "can't stop before all the pieces of a pie are eaten" feeling. Rather short but involving and bringing a lot of positive emotions experiment, can't…
positive · reviewer's own thumbsView post →More of an interactive story than a game. The story was decent. But not much here. Production values were good.
positive · reviewer's own thumbsView post →The game is short, although not as short as Without Within. While it can be an entertaining diversion, it does not have enough meat to make it a main course. The story and VAs serve their job well, and some of the later levels can be tricky on ironmode. A few dollars is the right price, and for the entertainment value it is worth that.
positive · reviewer's own thumbsView post →Nice and simple game! Worth buying...
positive · reviewer's own thumbsView post →So... When's the sequel? Unhack has a very... Unique style of humour. For instance, the MC, you, use emoticons during dialouge. It's quirky and stupid, but really enjoyable for some reason. Also, having FULLY VOICED characters (and in english, no less!) really makes the 2 hours of fun all that more enjoyable. Xanthe Huynh, from Sword Art Online even makes an appearance. So if you love her performance, you won't be dissapointed. The gameplay in this is fast, but 'puzzle' really isn't the…
positive · reviewer's own thumbsView post →A game with a simple plot and ok voice acting. It should be a snaged at a cheap price if you can. Its not bad
positive · reviewer's own thumbsView post →As short as cheap as worth it! Good story that you won't know how it will end.
positive · reviewer's own thumbsView post →Quite a unique game. Don't let the anime graphics fool you, the gameplay takes skill ( especially on harder difficulty - casual players can play it on the easiest difficulty) and the story is quite good - it gets serious fast. Music fits in well and voice acting brings the characters to life. Also it's really cheap.
positive · reviewer's own thumbsView post →I quite enjoyed Unhack. It's an unusual little game. The puzzles are not difficult but I found them enjoyable. The story I found charming and humourous. The artwork is excellent and the music fits the game well. It's a relatively short game, but it's inexpensive. I thought it was well worth my time and money.
positive · reviewer's own thumbsView post →11/10 GG xD super recomended even Goku beacame ssj4 coz of excitement just seing it in steam ~.XD a must play action/vn/puzzle game :3
positive · reviewer's own thumbsView post →There's merit in the worst of it. i damn near lost my mind doing the mazes. Why would you tie the dialogue, you know, where you're telling the story. to specific moves? You destroy the rhythm of precision. Because it's not about step by step it's about solving the problem and if you can see the timing, the level is a river to sweep through, not puddle stomp. The solve was of course to have the ability to see past dialogue. Not grant infinite lives because if you happened to miss a key…
positive · reviewer's own thumbsView post →Unhack, developed and published by InvertMouse, is a creative fusion of visual novel storytelling and light puzzle gameplay that blends science fiction themes with a distinctive anime-inspired style. The game places players in the role of an “Unhacker,” a digital security expert tasked with combating a destructive virus known as the 5K Worm. Set in a futuristic cyberspace where artificial intelligence and human ingenuity coexist, Unhack tells a story that explores the ethics of technology,…
positive · reviewer's own thumbsView post →The idea of playing a visual novel that transitions into a puzzle game while still being a visual novel is novel in and of itself, even still in 2021. Story's a little thin and the art is a little rough (Unhack 2 looks great though!) but this unique and relatively short (less than 50 minutes on Normal) game is a treat.
