I actually REALLY like the game, it has a simple layout - yet is still very challenging at points. As a lover of physics games, and somebody that loves a good brain-strain - I found the game perfect for anybody that likes those games.
I would have to say that there are a lot of "mirror games" out there, but I think yours is very unique. You focused on the small details in the animation, and added a very calming music to go with the game. You couldn't have done a better choice.
