Good job coming up with (what seems to me) a super original concept! I had a lot of fun playing. 
The levels quickly became brutally challenging! I really liked that :D 
But if you decide to add more levels at some point, I'd love to see a few more easy levels to start the game off with. 
The game looks very nice btw :) 

Challenging Game  and love the visuals . Well done.

Loved the visuals and the idea was very interesting!

Smart and challenging game. I love the visuals, the sound and how the game makes me hate my-other-self for pulling the lever that will block my way out :) Got stuck on fifth level, but will give it another try.
