I felt that this game has more potential than actual...good stuff in it.
I didnt get past track one, because the first time I played I came in second, and the second time I played it lagged too much.
The game has a cool, accelerated feel to it, but it doesnt make up for the bumpy and uncomfortable driving style. Make a track without boundaries.
Also, the words "LAST LAP" were distracting. They should be smaller.
And lastly, a boost system would make things less...repetitive.
