The rotating circle has four colors. The circle can be rotated by pressing/tapping anywhere on the screen.
Tapping on the right side of the screen rotates the circle clockwise and tapping on the left side moves it anti clockwise.
Watch for the bombarding color balls that can destroy your circle. However, you can neutralize these balls by colliding them on to the matching color of the circle. If you miss, the game ends.
