I really liked the idea (I like puzzle games like this), but I didn't finish the game so far. At the time of writing this I'm annoyed at multiple situations, where I did not know, If my character (or the mirror guy) would hit the traps. A bunch of time it seems like I would be able to pass the trap, only to get caught in it (I'm guessing because of the animation). A good way to solve this would be to have a hitbox of constant size.
Then again, I'll most likely return to this one, since I really liked the puzzles and the design.
