A cool game. I am reminded of Opus Magnum by how it speeds up after a successful cycle.
I wonder why you chose to make it three-dimensional. All levels I played only made use of two dimensions, and I imagine some funny designs could have been possible, like making the game look like a PCB, or like a texbook circuit diagram.
A counter for the levels would have been nice.
Overall, the game works, it is intuitive, the soundtrack sounds good and so far does not seem repetitive (which is often a risk in such games).
The game idea is great, and with a bit of polish and a 2d-interface, I could see this being a fun mobile game to play one level at a time when I have time.
Thanks for creating this game.
