Ok I played it! I think it's a bit hard to see where the track is with the way the camera is positioned. If you moved it up and back a little bit it would be perfect, and not stuck on the car (also made it hard to see when in the air). Overall I just think it needs some polish, some sounds go a long way, especially for a racing game. But nice job, I hope you keep working on it!
Edit: Also I rolled over and had no way to get up, so I had to close the game and start over!
