Silly Little Car Game

Its a 2 player game but its not working very well YET. some things dont work like the kerb, you can go whereever you want without even getting obstructed by any of the stuff on the stage :P. But still if you think u could help me out then shoot ur comments at me.

The controls for Green car are arrow keys, and space for handbrake, and for red car its a,w,d,s, and shift for handbrake. there r only 4 scnes right now :P. i will keep on updating as i get far enough.
