From NGUYEN VAN HUNG:
EASY to play, HARD to master. Your life will be taken control by this game. There are two modes in the game: LINE MODE: Drag your finger to move the dot. Don't let the dot stay outside the line! SWING MODE: Just swipe left and right to make the ball fly. Be careful don't hit the obstacles!Have Fun!
