There is one thing about this game that's kind of bad, and that is that you have an upgrade feature, but upgrading is a bad idea. I think that a damage bar would be better, instead of making the car more uncontrollable (tires) or the game more difficult (engine). It's like playing Gradius with the highest movespeed. Graphics look nice, and the intro is a nice touch. I like the little sound effects you used too. But that music loop, it's pretty tiring.
