Interesting puzzle game. I don't really like the fact the environment does not have anything to do with the puzzles thematically or directly. Other than that the controls are the main issue:
- Picking up a cube resets it's rotation.
- Button to change output direction is too close to the pickup one, and I ended up accidentally triggering it multiple times in the last puzzle
- Maybe a simple inventory so I can keep all the cubes at once?
