This is a very nice mountain bike game set in the woods it may look easy but its not ,
The idea of the game is to try and ride the bike to the end of the track to complete the level in the shortest time. But without your energy bar reaching zero and you running out of time. To gain more energy to fill your bar up and to last longer pick up the red energy power-up pills that are set along the way these will increase you bar and make you last longer to reach the next level.
good Luck
