Circle PongPongPong 1.0

This is a little casual games.
Your mission is just tap one circle to make it stop moving and get bigger ,collide with other circles , and at last make all circles disappear.
Find good timing , one tap to decide win or lose!
PS: piano , drum kit , water 3 kinds of sound effects. It will cure your mind.
Hope you will love it .
Thank you very much.
