The main goal in the game is to collect all the green circles as fast as possible. Every second you waste you lose one point. You also get 3 lives, watch out and don't fall or you will lose 1. THere are several upgrades and special circles you can collect. These will be in a different color; red, black, or orange. Any level with a black background has low gravity. An extra life will be awarded once you reach the 5th level. Use the left/right arrow keys to move and the up arrow key to jump.
