Use arrow keys to move the purplish circle. Use space to jump. Easy right? Well, you have to avoid the red circles, the ones falling and the one rolling. If you don't you loose. Also, there are green dots. You have to catch them before it hits the floor or rolls into the brown circle. And if you don't do that, you loose. Good Luck!
Please tell me if there are glitches. Please read institutions before putting comments about glitches.
