great game, but there could be a way to wallride or maybe even "ceiling-ride" on a magnetic surface, and maybe you could add handling as a stat for cars, which could go with a new type of car designed for drifting. also, multiple maps like "urban" and "desert" would be cool.
i was expecting the toy car to start moving when touched, and this could have you be able to knock over the first one manually. other than that, great game!
