Good music, good enough art, awful puzzle gameplay. The tiles you get are entirely RNG so it's incredibly easy to just be handed garbage and not be able to really interface with the mechanics. A very well polished empty glass.

game is fun but terribly underdeveloped in terms of theory. yes its a porn game but the whole gimmick is easily cheesable. it sort of skirts around these issues by giving totally random blocks, but imo a strict block order per level or some other normalization would have been a better way to force a moral solution. score requirements should have scaled with the difficulty much harder, and there should be a infinite protection to prevent the most simple loops (limit reflects before the ball breaks). slime blocks are really cool but aren't utilized fully till the game is almost over. the porn is not bad, but not the best part style is great, but the animations are meh as you can tell i am much more interested in the puzzle game overall not amazing but i had fun. if the puzzle looks cool to you, you will probably enjoy it.

Genuinely, what the fuck is this game? The might be the WORST puzzle game I've ever played. Not even exaggerating. My best guess is that the designer wanted to make a puzzle but was too dumb to figure out a puzzle they made. So to get this out of the way, as far as an h game, its ok. Just some animations that play on the side as you progress. The biggest complaint is that you have to replay each 'level' twice. Once for nude, second for sex. Now time to rant about how dumb this game is. So the game is setup where you are given pieces to place to build a board. The pass the level, you need to generate enough points. You get points by directing a ball (piston) onto heart tiles. Score seems to based on the lifetime of a ball (not that it really matters). You place your initial piece which spawns 4 balls, one in each direction. You then get one new tile to place at a time. The first issue is that there are too many tiles which do practically the same thing. I genuinely don't know what sort of unholy machinations that the dev was planning for these to be use for, but there is zero reason to have a tile do functionally the same thing as 3 other tiles. This is made worse by the fact that tiles are completely random. You don't get to see the next tile and the tile pool is completely random. You can't actually plan ahead, which is incredibly important for a puzzle game. Why would you want to force a player to restart because they didn't get the 1 of 4 tiles needed to complete their arrangement but instead they just random crap 10 times in a row. The one thing to change up things is the different boards/stages which have slightly different layouts with preexisting tiles. And when I say slightly different layouts, I do mean it. Most of the time you can just straight up ignore the starting layout and do your own thing. Why would you want a player to adapt their strategy in a puzzle game, am I right? What's confusing is the theming and scoring of the game. Everything makes it seem like there is a time limit or limited tiles, but nope. You have unlimited time and unlimited (random) tiles. This is generally fine, but makes the scoring confusing. The best guess I have is that per wave of balls, you have to hit a certain score. If that is the case, why not just show that directly? Now lets actually talk about the tiles. You have the heart tile, which is used for score, battery which upgrades a ball to score more points, the skull tile which destroys balls, the water tile which ignores the effect of the next tile, and then like 6 tiles for redirecting the ball. The biggest problem with the tiles is the arrow ones which act like a one way passage and wall to bounce off of. This lets you create a area where the ball can bound back and forth and lets you form an infinite loop. Not like its that big of a deal though, not like you can score infinitely just by doing that. Oh wait you CAN do that. By doing so, you can basically clear every level with the exact same strategy. You just need 1 of 2 tiles that let you do it. Or of course you could just form a really long chain of hearts like some sort autistic game of snake. Because fuck it why bother trying to make 4 optimal paths when you can make just one that goes around the whole level. Just make sure to save one spot for a battery, if you get lucky. Either way it very easy to meet the score requirement and move on to the next stage. Wait, why isn't it moving on to the next stage. Oooh, because fuck you is why! Even though you met the score requirement and can't alter existing tiles, you have to fill up the board anyways. Doesn't matter if your score is the in game equivalent to finger blasting their anus into oblivion, you still have to place a tile in every single square. Puzzle games are suppose to have the player figure out a problem and solve them with the given tools by figuring out the best way or various ways to use their tools. This game just says fuck all that and give the player 10 fucking screwdrivers of various sizes then tells you figure out how to escape the room. (The door was unlocked)

Well, no, the game is just super. It really suited me. And the music is cool, and the graphics. I didn't understand the gameplay at first, but when I did, I even liked it, it was a pretty cool puzzle. It's a pity that the game is quite short only

very nice music, good art, nice animation style and decent gameplay. Though you can cheese a lot of the gameplay, by using closed loops and just bouncing the 'pistons' back and forth, it's still engaging and fun.

Came for the content, but stayed for the music. A very creative puzzle game with well-built mechanics to challenge both of your brains. The censorship might be a drawback, but overall it's a very good game. Deserves a 5-star rating for all the musical bangers!

Is it a good PORN game? ... Meh, not really. Is it an absolutely banger soundtrack with some mildly horny animations and some (to me) genuinely fun puzzles? Absolutely. Definitely don't expect a hardcore wank but i'd say give it try to just hear the music and stretch the brain a bit until you find the magic pattern.

Great puzzle game to stimulate your upper and lower brain. Its unusual and has some creative mechanics. The visuals are really pretty and music is a total banger . I had initially intended on giving it 3 or 4 stars because of censorship but since then I made a patch so it can be experienced fully and as such its a 5 star game.

Overall 3.5/5. Its a puzzle game with literal porn on the side. Play for the gameplay and you will probably find yourself forgetting the porn. Gameplay 3.5/5. If you are into puzzle games you will probably enjoy this one. The puzzle was new for me, so learning and experimenting with the mechanics on levels that get more complicated were challenging and enjoyable for me. The puzzle is difficult to describe, best try it if you are curious Story and Characters -/5. There is no story and all characters are basically just eye candy Art and Adult Scenes 2/5. The visuals itself look good, however there are barely any scenes in this game.

music slaps art is good puzzle is surprisingly addicting (albeit there's an exploit that trivializes the game) really, the only reason I took 2 star off was the actual hentai content is miniscule. outside characters stripping and swaying their hips sensually, you basically have 5 sex scenes, 1 for each character.

I just wanted to write. What a cool game. I love the rhythm of the game, especially with unusual mechanics. So the local puzzle fascinated me. It's a pity that she's so short. I hope the author will expand this game further and make the new part even bigger and more diverse.

Piston is really fun, and I enjoyed the hour or two that I put into playing it. Once you get acquainted with what all the pieces do and find good strategies, you'll be cruising through most of the levels with ease. The sex animations are fine, and there's only four girls (technically five but there's no levels for the fifth girl) in the game right now. I wish there was more, but what was here was satisfactory enough for me to enjoy the game. You can fap, but this is not the kind of game you cum to, though.

While unique and simple, too random to be worth putting up with. Visuals are great and gameplay is interesting idea-wise. Not much else though. Censorship and buggy settings (audio, language) do not help. Small simple game with good animations, if gameplay fits you, it's great and might be worth trying.

At first I was interested in the puzzle aspect, played a few games that that is all I cared about, but then I realized its all rng. So if you really don't care you can just spam the same strategy for the whole game. I'm unable to upload an image for some reason but the strategy is essentially Spawner then an arrow then heart then arrow back the other way "O-><3<-" it causes an infinite loop of the ball gaining power. So it gets 1 star for the actual game part but 1 more star because the H is alright.

An alright game, gameplay mainly consists of making good chains with the balls to up the meter and clear the stage which is also poorly explained and took a good deal of testing to roughly figure out how it works. While there are 5 characters, you only get one scene with them each so if you find a girl you like, you only get the one scene and thats it. Each girl has 3 stages which you can return to each as sort of a checkpoint if you fail to pass one, but the extra bonus stage (the actual sex) are a gauntlet with NO checkpoints, its all or nothing for these. Art quality is alright, not insane but not terrible either, just simple shading/coloring which is enough for a small game as this. There is one problem i had however, the rng regarding block types. since there a plenty of blocks that do unique(ish) effects, its important to understand how they work to make use of them in your chains, however, there have been runs cut short due to not getting a specific block i needed to complete my chain, while you have plenty of tiles to place unneeded blocks and reroll the dice, its still possible that one or more block types doesnt appear at all. Overall its a neat small and short puzzle game first and a porn game second, worth a try if you enjoy puzzle games and dont mind the RNG. A good 4/5 game that couldve been improved with more scenes with each girl and tweaking of the rng or guaranteeing each block type appears at least once.

Short fun game, I genuinely enjoyed the gameplay, the only thing I dind't like was that it ended. You can finish the levels early if you got enough points, I ended up playing some of them until the very end just for fun. The art is really good, maybe with 3 or 4 extra girls or more art for each one it would've been perfect. The concept is so good that I really hope they release a DLC or a second part in the future.
