You are the blue circle. Move using the mouse. Be quick! Try to touch the friendly green circles. Each translucent one you touch gives you 1 point. Avoid the enemy red circles. Each translucent one takes 3 points. Score more than 20 to win. Score less than -20 and you lose. Press the space bar to start!
Should I make the red circles friendlier like -2 instead of -3?
