This is a race against time itself! You have to hurry up and reach the end of the level before the time runs out. You can get more seconds by collecting power ups or you can buy them in the upgrades screen. You could also improve your speed or your NOS power which will allow you to cover more ground in the time you have. There are three great levels to complete, so hurry up! Have an incredible time playing this amazing game!
Look for the in-game instructions.
