One of the worst games I've played.
Basically, you are a car and you want to avoid obstacles and then upgrade your car with the money you earn to race better. This sounds pretty cool and typical, but because the controls are messed up and the graphics are so terrible, there is nothing really to like about this game besides the fact that it is free.
Some obstacles seem like they are impossible to get around while at other times you can go up the walls and just stay there for the entire level. The powreups don't really do anything and upgrading your car is pretty much useless.
If you have downloaded this game, don't waste your time playing it. If you haven't downloaded, you haven't missed out on anything.
