First of all: you're damn fast!
I really really like the game
I'd like that you could swipe from one button to another. You know, that you can change direction without releasing the finger and touching again...
maybe you're aware of it, but you should pause the music in the pause event (ie: lost focus). I've received an incoming call (actually a call from my job) and the music was still playing
And I really like the music, I'm still looking for one that fits in my game
