i see this has potential.
so i'll keep it going, my tips: draw it better (if you can't, i can help, just send me your email through a private message.) install a menu, more levels like you said, and a 3, 2, 1 before you go, it's there for a reason, and maybe more music tracks to pick from, and faster movement and a moving background, put that together, you got the next racing hit.
