Nice! Good graphics, love the audio. Would enjoy the game more if it had things to collect along the way (think of Jetpack Joyride). Also when you get hit you should still be able to move. Other than that, pretty cool.
Good idea about collecting things, I don't know why I don't think about it... regarding the movement, initially it was like that, but I thought it would be better if I removed the movement, but it looked in vain
