This is an extra quality game. You can play in four different worlds and be one of 15 cool characters. But first you will have to unlock them one by one. Each world has five levels and each level has two different tasks that you have to fulfill and earn a medal. To do that you will have to win at least bronze medal. Use the arrow keys to steer your bike (up arrow- accelerator down arrow- brake left/ right arrows-make balance) and space bar to jump. Press P button to pause the game and reset if needed. Follow the map on the left bottom corner. Get cash and spend it wisely on things that you think are most crucial: speed, acceleration, nitro, agility or jump.
