Looks good so far! Good frame rate and everything so far! Power up was good! My suggestions. I know this game is early in development, but you said you were looking for suggestions as your not a race car game type.
- Add skybox
- Lower the wall way down just above the vehicles height, then add a sort of 'bleachers' with the crowd. (Add some crowd noise)
- Engine sounds. Lower gear, medium gear, high gear. All you need. Some good ones in the TGC sounds pack.
Look as though the car in front of you had some decent AI on it. So nice job on this so far!
