This game is very poorly made.
The controls feel incredibly sluggish. Looking around feels "off," as if there's mouse acceleration, and movement is fairly floaty. Passing through a doorway causes the game to grind to a halt for a second to load the next area - not necessarily a huge issue, except once the loading is done, it eats your inputs. Every single time you pass into or out of an area, you find yourself not moving anymore, you need to let go of W and press it again. Checking for your inputs after a loading screen is basic stuff, and combined with the slow movement speed, it just eats away at one's nerves.
All of that could be forgiven if the puzzles were good. They're not. The very mechanics of the game are bad, to the point where I don't actually know how you're intended to solve half of them (I managed to exploit almost all of them - we'll come back to that). The game starts off with you placing and removing blocks to platform, basic stuff, but satisfying. Before the game does anything interesting with a mechanic, about a fifth of the way into the game, the entire concept of placing blocks is completely abandoned until the very end.
The majority of the game is spent using green "blocks." The gimmick here is that you can't actually interact with the blocks, but turn any collection of your placed blocks into pipes. This is where the entire premise of the game falls apart - the pipes themselves are subject to physics, making them completely unreliable. And the game expects you to rely on them. You need to make pipe bridges and cross them, without them falling over, or bugging out and falling over, or without you sliding off. You need to jump up pipe pillars without them toppling, or without them bugging out and toppling, or without you sliding off. Making pipes and pushing them around is a major mechanic here (I think), but pushing them is a trial of misery. It's a physics-based puzzle game where you have little control over the physics.
In one level, I made a seesaw with an L-shaped pillar at one end. It was perfectly balanced. Apparently the player has no weight, so it was stuck. Until I pushed the pillar at the end, at which point that side sunk down. I was pushing the thing I was standing on and moving it around. Because physics.
Towards the end of the game - I'd say the final fifth - you get the ability to place antigravity pipes, which are exactly the same, but they go up. Quite frankly, this is the only point where the pipes came close to being enjoyable - the fact that you could use them as elevators made them much easier to work with, and there were some good ideas involving using both sets of pipes. Ideas that would have worked MUCH better if they were blocks, or if they had at least followed less realistic physics that followed more predictable rules.
There's also another white blocks section thrown in the middle of the red pipe section, as if the developer suddenly remembered they had them in the game. I believe there is only a single puzzle in the "green section" that had white blocks, and it only had a single one. There's basically no puzzles in the game that actually take advantage of combining the white squares with the pipes - presumably because they'd be too easy to exploit. This game is actually terrified of letting you "cheat" - you can't jump and place a block under you, nor can you peek over the edge of a block to place a new block there. Abilities that are arguably as standard as jumping, and the game restricts them. Which, like before, wouldn't be a problem if the solutions to the puzzles were logical - but I don't have the slightest idea how you're "expected" to solve most of them. I ended up solving most of them by cheesing them, sliding pipes into awkward positions and making tight jumps, often ignoring most of the space I was given to work with.
Were those actually the intended solutions? Possibly. But while it can be liberating to solve a puzzle in a way the game didn't intend for, it's not really gratifying when it doesn't feel like there was ever actually an intended solution. Ultimately, the real crime here is that the game takes away player freedom to prevent players from breaking the game, yet the game is still easy to break, so what was even the point?
And a minute to talk about the final "puzzle" (if you're willing to call it that). You have to build an elevator to go up a long tunnel. So, naturally, the game gives you tons of antigravity blocks... and green blocks, and even white blocks. Why? Are they useful here? Am I missing something? So I made an elevator, and it immediately went topsy-turvy. I guess your player model actually does have weight. I made an elevator with railings, and made it a bit higher before falling out... just before the elevator passed through the ending trigger and disappeared, taking its precious blocks with it. By the way, the game has no save feature, you need to exit to the menu and reload whenever something like that happens.
Brief mentions about bugs: aside from the physics being terrible and the loading being a pain, I've had pipes spontaneously jump into the air upon placement for no reason, I've had the ability to construct pipes completely disappear and require a restart, I've fallen through the world (and as far as I was willing to check, there's no killplane down there), and been able to grab blocks through the phase fields when you're not supposed to. Also, if you press the mouse buttons during the credits, you can hear the sound effects of your gun. (Speaking of which, the train in this game has the goofiest and least-fitting sound effect ever).
Oh, and the puzzles in the second and fourth-to-last screenshots don't seem to be in the game.
This perhaps became more of a rant than a review, but I was extremely disappointed by this game. I hate judging games by their price, but there is absolutely no way this game is worth close to the $13 pricetag. It wasn't even worth the less-than-three hours it took to complete.
