That was cool ! A nice little puzzle game with original mechanics ! The concept was sometimes a little bit hard to grasp : in the level 5, I often couldn't move my character like I thought it would... Maybe I didn't understand the physics correctly, but the solution I came up with seemed more "cheezy" than a real intended way ^^'.
Nonetheless, that was a really cute and well-done game, with a nice idea. Congratulations !
