An little and addictive dot and circle game.
Tap left half screen to clockwise rotation, tap right half screen to counterclockwise rotation. When circle rotates, dot's orientation will be changed, you need to tap left and right in the same time to control dot, and eat the coin inside the circle.
Maybe it's a little hard when you play the first time, be patient and play several more times, it will became more and more easy for you.
