    If you take a brief glance at a video for this you may think it's all about timing and dexterity but it's nothing of the sort. This is a puzzler through and through. You have two rooms: orange on the left, blue on the right, with a jellyfish in each. The two rooms are usually identical, sometimes there is a small difference. Using your left and right controller sticks, you have to move both of your jellyfish to the exit portals at the opposite ends of the rooms. Doorways are guarded by…

    This is an excellent puzzler with a very enjoyable meditative soundtrack (the music and atmosphere reminds me particularly of OSMOS). I found it to be very well paced, with the new mechanics building nicely level over level. Some of the more difficult levels consistently mess with my brain. Puzzle/Stealth fans should abosolutely check this out. I know the dev, have watched this game develop, and played it multiple times at various public demos. It is truly a must play for me and should be a…

    For a while this is an intriguing puzzle game, but eventually, as seems inevitable, it also decides to be a twitch game -- where being able to come up with the solution is not enough, you also have to have nearly-superhuman precision and reflexes to time the solution just so. Which means if you don't have that ability, the fact that it's a puzzle game doesn't matter, you cannot play past whatever point you get stuck on. Pity. Also, those blurry hard-to-see comic strips not only don't fit, they…

    barely just opened, still, hadn't seen big news as per gameplay. saw a beautiful artstyle, tho, gorgeously chilling colors and somewhat classy ambient. also felt my two different brain hemispheres working. super recommended, one of those you'll come back to, like a little comfy chilling corner. awesome gift from Killer Joe/Blue

    Smart "two-sticks" puzzle. Gradual new features and way to make you struggle. Sadly the visual and overall experience is a bit limited in term of global experience. A good enough puzzle game but the competion is though in this genre. Not recommanded at full price.

    It's pretty good, worth the priceDeserves more love from fans of abstract puzzley/stealth stuff. **I don't think it would be any fun without a proper controller (with 2 joysticks). Each level is split vertically into 2 halves, as you can see from the store screenshots. You control 2 spheres (jellyfish?) simultaneously, and need to get each to the exit on their side of the board. For most levels, you can usually split up the task to work on one side at a time, alternating back and forth, but…

    I'm on the fence with this one. For the amount spent both cost and time wise it wasn't bad, and the gameplay wasn't bad, but it was much much easier than I was expecting. You very rarely need to control both sides simultaneously unless you wanna complete it faster, and that's what I was wanting from this game. There were like... 2..? levels that required it. All other times it was just move one, then the other, then back to the first one, until finish. The 'story' wasn't very engaging and was…

    I am 32 years old. My ex-wife and I have a daughter together, and we adopted our son together. Both are now 4 years old. When we were going through our separation, I felt lost and unhappy. I was self-destructive. One day, I was so angry with everything spiraling out of control that I punched a concrete wall in a moment of overwhelming emotion. This resulted in breaking my fifth metacarpal in my right hand—the hand I worked with, played games with, and used to carry my children to bed—the hand…

    A casual puzzle games with some nice ideas that in the end amounts to nothing. I really like the idea and the concept but to be honest this is too easy. Until the last chapter I had a feeling like i was playing a tutorial.If you are looking for a challenge you wont find it here.

    It takes something unique in a puzzle game for it to attract my attention. Usually I overlook them when they present themselves like so many others as something that uses the same tired mechanics of other games and puzzles and adds the 'twist' of being extra difficult or painted purple. When I saw the simple but fairly unique design of Semispheres, I had to try it out. I don't know if I've ever had a moment of 'reading a book by its cover' being met with such accuracy, but Semipheres…

    It's an interesting entry in the "two ships at the same time" genre, but I liked Schizoid for Xbox way better. The puzzle design is weak and the story just isn't pulling me in. Most levels are simple enough that you would expect that there's only a single solution that requires some degree of cleverness to spot or dial in, but that only happens one time in ten. The other 90% of the time in this game, it just feels like "I don't get it--I can just do this, or this, or this, or this", and a…

    I enjoyed playing Semipheres. It features 50+ levels of mainly logical puzzles that are centered around controlling two balls on separate fields with the same architecture and making use of the items that are available on each field so that each ball can reach its exit. There are five basic game mechanics that you can use to manipulate the surroundings. The combination of these mechanics generally provides for interesting problems but even though I had fun playing the levels, there is one…

    I came primarily for [url=https://siddharthabarnhoorn.bandcamp.com/album/semispheres]Siddhartha Barnhoorn's awesome ambient music, but the rest of the game is good as well. It's a relatively minimalist puzzle/stealth/atmospheric game. NB for those not playing with a dual-stick controller, it's gonna be a real coordination challenge....unless I'm mistaken and it's a challenge regardless. Either way, even if you don't have dyslexia this game will make you feel like you're playing with it!…

    A really cool and zen puzzle game. It reminds me of Brothers: A tale of 2 sons with controlling two characters at once, except each has its own side of the screen now. There's some interesting mechanics that take advantages of that too, like portals, space swapping, and line teleporting which really demands you to think about what you're doing. There's also a lack of filler content which I highly appreciate as you go straight to puzzles. The soundtrack is fantastic as well, very calming and…

    Straightforward puzzler with an interesting idea and decent execution. This game is a bit above adequate in most respects: nice graphics, nice sound, nice puzzles. But, outside of the actual idea for the main mechanic, nothing stood out as particularly stellar. None of the puzzles were particularly complicated or required much coordination or timing. Only a few puzzles hinted at the sort of complications they *should* have been building toward. They introduced some fun mechanics, but didn't do…

    Finished this in no time at all. Game was a good idea. You may find it more difficult if you struggle to do two things at once. If not, decide if 2 hours of gameplay is enough for you based on the price.

    This game is a really fun casual game. I found it through my local subreddit as the developer had posted. He was super engaging and that caught my attention. 1st thing I was concerned with is my general hate for controllers, and this game plays GREAT on keyboard, so fear not! I went through the first 12 levels or so and its super fun. A casual break for your mind, super low key, and an actual great minimalist soundtrack.

    A methodical & chill puzzle game with stealth. The game really eases you into the difficultly but introduces new mechanics at a good rate. The best part are the controls as you control each sphere with a different joystick. I highly recommend a controller not only for the joysticks but because of the analog movement, it feels more fluid. I made an informative video: https://youtu.be/eKttvTt3UBk

    Tight little puzzler. Levels are tough, but fair. The control scheme lends itself really well to a split-brain theme, which can get pretty hard. There's not much of a story, but that's ok. It's just good puzzles and vibes. See all my reviews at [url=https://david.reviews/]david.reviews

    The game system is unique, so it was fun at first. I personally didn't enjoy it much because the action elements are less than expected and it's pure puzzle I gave up playing because I couldn't solve the puzzles. If you like puzzle games, this would be fun.

    A short, but beautiful puzzle game with an unique split-screen mechanic and a touching, heartwarming story. Played with a keyboard, without a controller, but that didn't seem to hurt the experience in the slightest. On a side note: a bit disappointingly, situations where you have to control both... glowy balls at the same time happen all too rarely - most of the time you can complete the level by focusing on just one of them at the time. Still, the few times it happens it presents quite an…

    This is a great puzzle game. Not too long (took me less than 3 hours to beat) but the levels felt good and never too difficult or too big to enjoy them. I totally recommend it to puzzle lovers. It is really better played with a controller since each analog joystick is used to control a character

    Semispheres is a lightweight puzzler with some clever ideas. You need to guide a pair of jellyfish to their respective goals in parallel versions of a level, one with each stick on a controller. (You can also play on a keyboard, I guess. It probably works OK.) In your way are guards with stealth-game vision cones that send a jellyfish back to its starting point. The setup sounds like it could result in a thumb-twisting dexterity challenge, but that's not what this game is. Just a handful of…

    You control two orbs that interact in various ways. The game is not that hard and should take a few hours at most. Its a very relaxing puzzle game. Some elements require coordinating the movement of two orbs together, but its not super hard. I enjoyed it, I think its worth it on sale. :)

    I played through this game in one sitting and found it very enjoyable. I didn't try it without a controller but you'd proooobably be okay without one? You control the two "things" with two joysticks, but I can't remember any part that took extremely precise angles or coordination so wasd/arrow keys are likely adequate. There are two other buttons necessary (shoulder buttons on controller), so thumbs/pinkies would be needed too on keyboard. Definitely recommend controller if at all possible,…

    Tight, clever gameplay. Makes you feel smart when you solve some of the devious later game puzzles. Love that it doesn't overstay its welcome; it focuses on exploring the parallel mechanic and doesn't give you hours of repetitive filler. The narrative comics are simple yet engaging.

    FULL DISCLOSURE: I know the developer personally and have seen the game grow from a prototype to final release. Semispheres is mind bending. I have never played a game that tests my puzzle solving skills as well as my physical dexterity at the same time. The first time I picked it up it felt so foreign to be controlling two characters at the same time. It really surprised me how I got better and better at it over time. The puzzles are supremely clever and the mechanics are taught to you as you…

    Full disclosure: I know the developer and I have played in development versions of this game in the past. Semispheres is a great puzzle game about planning ahead. Attempting to navigate both halves of each puzzle simultaineously can occasionally tax your dexterity, but very rarely are you required to do that. Most, if not all, of the puzzles can be solved in small steps, moving one stick at a time. If you are into puzzle games, but are worried that splitting your attention between two…

    Full disclosure - I had the honour of getting to play this at GDC in 2016, am a big fan of this developer, and was eagerly awaiting the release. I've always been impressed by this game. To me, this is a gem and an example of a really well made game. It is easy to play, and difficult to master. The soundtrack is perfect. The art is cute and unique (and you'll always recognize a semispheres level when you see one). I'm a bit old, so it really does do a bit of a workout on my brain. If I…

    Semispheres by developer Vivid Helix is a 2D puzzle game that applies the concept of split-screen to a smart, fun, and relaxing experience. Each level splits your computer screen in half, with one of your “semispheres” on the left side and the other on the right. If you are using keyboard controls, the WASD keys control the left semisphere and the arrow keys control the right semisphere. (You can also play with a controller, which is what the game recommends and what I used. Each joystick…

    This is an incredibly cool puzzle game with some very interesting mechanics. Watch the video - it gives a better overview of the play mechanics than I could describe. There's no real story, but there is a cute little comic-book that's revealed page by page as you progress. It doesn't tie into the gameplay at all, but it's enough to keep you wanting to see the next page. The one problem with this game is that it's short.

    I really enjoyed this game. The puzzles are all really well designed and have a great flow to them. It's obvious that the developer has clearly put a lot of time and effort into them. The main gameplay of controlling two characters at once is something I haven't seen before and it works great. I never felt it was impossible to control both at once. The price is just right as well. It seems like a bargain that this is selling for what it is. Overall I really recommend checking this one out!
