Circa Infinity

Arcade platformer where you navigate inward through concentric circles. Each level has you jumping between nested rings, timing your leaps to dodge patrolling creatures as you work toward the center. The circles flip between black and white as you pass through them, and enemies move in set patterns you'll need to memorize. Fifty stages gradually increase the speed and creature density. Five boss encounters break up the progression with their own mechanical twists. A speedrun mode lets you chase faster clear times once you've learned the layouts. It's reflex-focused rather than puzzle-heavy—success comes from reading enemy rhythms and committing to split-second jumps.
