Its ok...
This game is definitley better than the first because of more game modes and it was also more challenging then the first. I gave you an 8 because the backgrounds were kind of bland and boring(I do know that was the style you were aiming for). The music got repettive and wasn't very exciting. Overall there were no bugs in the game (which I love!), and the car (or kar) had almost real time physics... plus I like the booster on it! Overall Good Job!
