Great job! I really liked the game design, this is actually fun to play! Reminded me of an "Impossible game". I'd agree with that "time stop" point. Maybe it would make gamedesign more smooth. Also had a problem when sliding off the edges :) If it's a square it should collide as a square But thats just a nitpicking. As I said, gamedesign is great, awesome entry!
Check out my game too if you have time!
