    Si vous aimez bien les jeux en co-op (à distance), je viens de finir Unboxing the Cryptic Killer, un petit jeu sympathique d'énigmes qui se finit en quelques heures (et qui est pas cher du tout en ce moment)

    Play as one of two investigators: Detective Old Dog (actual government name) - a man with a wildly varying array of accents, or Ally - a woman who becomes more and more Scottish as time goes on, which is an understandable stress response. The game is fairly short (it took us about two hours) and the story lacks some... polish, let's put it that way. But the puzzles are fun and engaging without being frustratingly difficult. I've played my fair share of coop puzzle games and had quite a fun…

    Amazing short co-op puzzle games. The art style is top-notch, and the puzzles are very intuitive, unique, and challenging without being too frustrating. It took my friend and me about 6 hours to complete 100% of the achievements.

    Sorry, it's got some fun puzzles but it also feels like they made it just long enough that you can't return it after you beat it, but not long enough to feel satisfying. And, I dunno, I saw the ending from a mile away. Very thin story.

    A solid 7/10 for us! It's rather short, so I'd wait for a sale. We completed it in just about two hours. We may go back and swap places, but it'll have to be later down the line so we forget the puzzles. I may not have bought the game if I had known it was this short, but I won't force a refund even though I could. Doesn't seem fair. This game is more for amateur or intermediate puzzle solvers I think. The puzzles were mostly pretty easy. The only thing that would be holding you back is how…

    Very good co-op puzzle game. You need to work and communicate together to find the solutions. I would like to say, you need a good partner but not too much. Because most of the puzzles are giving the solution away quite easily. Personaly, I understood what we needed to do at first sight most of the time, they are not too cryptic which is good, I guess... I liked most of the puzzles. They seem easy, but not too much. You need to think one step ahead, and I really liked that twists in the some…

    I had a lot of fun playing Unboxing the Cryptic Killer. The puzzles are really well designed and feel rewarding to solve. I completed the game twice, once as Ally and once as Old Dog, and both playthroughs were enjoyable. You can really tell that the developers put a lot of effort into this game. What makes it special is the teamwork aspect. Solving puzzles together with your duo (in my case, my best friend) is the best part of the experience. Communicating, thinking together, and putting…

    Decent game with decent puzzles. Worth a try for the puzzle lovers. I wish that the puzzles had some random factor to them. Replaying as the other character is not fun as the puzzles are exactly the same.

    Me and my partner had a splendid time with this game. The full price is absolutely worth it - the game is perfect for a fun, cozy evening with a friend or partner, and a much more affordable alternative to an escape room. The discounted price is a bargain. The developer also offers a free prequel to this game, so you can test if the gameplay is something for you. Unboxing the Cryptic Killer is a co-op puzzle game for two players, similar to a digital escape room. You're separated from each…

    NO SPOILSERS! DONT WORRY! Absolutely amazing game. Incredibly fun, definetly worth the 6 euros. The puzzles are well made, not too easy but also not too hard. The hints are very nice as well slowly pointing you towards the answer not giving it straight away. The only thing I didnt like is that when you type the code that is a 4-digit code, even if you know 3 digits the last one you can sort of brute force and just try until you get it. And when you are desperate you just try until it works. It…

    The premise is good, but the puzzles aren't good. I only had 1 or 2 "ahhh I get it" moments. The video game puzzles are fun. There is variety in the puzzles, but morse code? Flag semaphore? This is not fun. But the price is right. 5.5/10

    Short but extremely fun! My husband and I had fun solving these puzzles and, while they were challenging, only needed the assistance of the hints a couple times to complete the game. Great way to spend a few hours, wish it was longer.

    Can write the same as about the prologue game: fun for an evening with a friend, looks good and the puzzles puzzles are not too difficult, but still have you pay attention and talk about them. The story is alright but is more there to give you a reason to solve those puzzles which it does well.

    This game is the second in the series (the first one is free, its called unsolved case). This is an amazing coop puzzle game, and I enjoyed it. It is a bit short, but pretty good overall. I also like that these games are on mobile and other platforms with crossplay, so its easy to play with a duo.

    Got this game when it was on sale for my girlfriend and I. It was a great way to connect while we were long-distance and since it saves in between rooms, we were able to do it over a few weeks when we had time. The only thing I noticed that was off was that when we used hints they were confusing and not well written. I enjoyed all of the puzzles though!

  • Steam user Steam user …3754Steam reviews · May 7, 2026 · 2 h played

    The puzzles are not very original and become repetitive quite quickly. Sometimes they are too easy, other times tedious and unintuitive. The game is also very short. The main positives are the low price and the nice art style. I would leave a neutral review if Steam allowed it.

  • Steam user Steam user …0746Steam reviews · May 3, 2026 · 2 h played

    The price of the game does not justify the content. It is a game with 0 replay ability because the codes are hard coded (rather than randomizing shapes and numbers). The puzzles, albeit sometimes interesting, take about an hour to fully complete. If the game is half off, maybe it is worth it

    Delightful game! there were only a few puzzles that really had me and my friend stumped, but the rest were solvable with few leaps in logic. And the hints helped get us on track. Very worth it in my opinion, got both games on sale for seven dollars. Play the free prequel if you're uncertain. But if you enjoy a good ol' escape room, this will be right up your ally.

    Played with a friend. We really enjoyed this. You are each given different pieces of the puzzle and have to work together to solve them. Most of the puzzles are not timed so it is not stressful. Loved it so much we are going to play the other games in this series, and any new ones that come out. Great for a game night. Can be done in 1 session.
