Great "Burnin' Rubber/Bump`n`Jump" clone with good control and I also like the look of the cars. A selectable-function between music+sfx, only music and only sfx in the game-menue would be nice, together with a new sound-effect, when the player bumps into other cars, or other cars into him, because at the moment, this happens in silence. Really nice work and the feeling of acceleration comes across well here, by the way.
I do have one small criticism. Forcing opponents off the road, causing them to lose a life in this way, is significantly harder, than in the other two mentioned games on the C64. Of course, you can kill them all quite easily, by jumping on them, but pushing them off the road isn't easy to pull off. But maybe that's how it's meant to be? Good game, in any case. And by the way, a simultaneous 2-player mode would be awesome here.
