Not a bad game at all. First, if you're on the fence about this from the screen shots, this isn't for you. This is a challenging puzzle game through and through.
If this sort of "use pieces to get things from points A to points Whatever" gameplay appeals to you, this is pretty fun, and is what you might expect. There is a demo, so you can decide if this game appeals to you.
Bear in mind, though, this game has a pretty steep difficulty cliff right out of the gate. I was having brief trouble with 1-star difficulty levels early, and a lot of the early levels will either require knowledge of pathfinding, or teach it the hard way to players. Even early manipulating blocks are presented with the "here's a new thing! Figure it out yourself" instruction. This is not a casual game.
This is, for those looking for a challenging puzzle game, a neat idea.
Graphics have a solid, consistent style. Music is actually pretty good, never mind for an indie puzzle game. I don't much care about these for a puzzle game, but they're both capable here. Controls are a bit clunky. If you are those who wants controls to work for your specific style, instead of being ok with dealing with a not-quite-super-intuitive interface, you might have some issues with constructing your solution at times. I personally didn't much have a problem with it, but I know some people who will very much like this game's concept might have issues with the interface.
Each puzzle after the brief tutorial is rough. And then, once you learn what the game is maybe expecting of you, challenging. And then, you'll come back to the game and solve something you struggled for almost a half hour with, a single puzzle, immediately, after time to sleep on or ruminate on the level. I've only gotten to the later parts of the first half of the main pack, but I can see this idea being the norm for this game. And "only" 65 or so levels becomes a complete, double-digit or so hour game when each level takes several minutes of thought, and possibly pencil and paper, to complete an individual level. And then, you can use what you've learned from that difficult level to beat more easily/accessably solved future levels. And the rare past level you chose to skip.
And this is a barometer for which I will judge harder puzzle games. I'm fine with learning the ropes for them, and once you do, this game becomes a game where you have a eureka moment randomly on a level and then beat said level reasonably quickly, after staring at it and trying hard for a while on with no progress.
The dev is also very receptive to the game's users, including being, in the past, willing to allow previous purchasers of the game elsewhere to get a Steam key for free when this was first put on Steam (From what I can tell from the game's discussions forum). I got this game during a sale several months after this went on Steam, but for smaller-scale games like this I like seeing how the dev(s) act with roadbumps in the release process. This game has, in the past, had a strong dev interest in its playerbase. I definitely consider this in my opinions, and this game passes with flying colors here.
And on that "graphics" front, the spray-painted "29" in the game's interface for the challenge mode is a subtle change that almost represents this puzzle game's strengths too perfectly from those who dedicate the time to complete this game. Originally, the challenge was to clear the game with 3,000 tiles covered, but because of the community, it was discovered that one could beat the game covering (as of now) exactly 2,900 tiles. It's worthy of optimisation; and that's pretty big for a game that's not super-big to achieve; an ultimate challenge that even the dev underestimated, to an extent.
I'm digging this. I might update this review as I play on, as I've not gotten past the first screen. But yea, this game is difficultly engaging for a puzzle game fan like me, almost to the point where I'm learning a bit about data structures (and am inspired to learn a bit about types of coding) from it.
