Very interesting puzzle game with some challanging puzzles where you have to deconstruct them in an interesting way to find the solution. It also feels like everytime you try something you figure something out (very nice). It would be really nice to have an "undo" so that you don't have to reset everytime you figure what you've done wrong.
Unclear if I got to the last stage (the empty room with the moving light), it feels like I'm missing something.
The controls could also be a bit faster so every move doesn't feel so heavy.
Very nice game and concept!
