Circlen is a one-button game of skill where the goal is to complete each of the 40 levels by collecting as many stars as possible. Stars are used to unlock later levels, and there are 3 stars per levels. Dodge various obstacles to collect the stars and then travel through the exit portal.
Your circle will start each level spinning in a clockwise direction, and clicking changes direction so you can move around. Fast reflexes are needed, especially if you want to collect all the stars in the later levels. Do you have the skill to beat all 40 levels and collect all 120 stars?
