That game is hard, but not in an unfair way! You always feel like you'll "get it next time!".
Once you understand the red borders are timers, the rest comes naturally.
I love the infinite zoom-out effect you made, it's weird at first, but it really makes you feel that you are the both the map and the character.
It makes me think a lot of Geometry Wars, in a good way.
Excellent job! =D
