Its called The Rotator for a reason.
The Rotator will test your ability to multi-task and react quickly. Dodging between the arcs would be hard enough on its own, but the entire game is inside a circle, and if you arent careful it will roll right off the screen!
Touch the screen to move around the circle, dodging red arcs and touching blue ones. Tilt your device back and forth to keep the circle balanced. One mistake and its game over, so every millisecond counts.
