Infinite nitro. All features unlocked.
Choose your favourite character (spiderman, Michael, etc., do you know all of them?) and bmx bike to racing. You will get extra energy by stunt, and you must gain the first for next level. It's really a challenge to finish all levels, can you do that?
Use arrow keys and Spacebar to play, LEFT: Lean forward, RIGHT: Lean back, UP: Accelerate, DOWN: Brake. SPACEBAR: release energy and accelerate.
