This is my fourth application which I published in android market. This is a ping pong game. By dragging a green racket, hit a ball! When a ball collides with a target ball, it erase a target. The goal is to erase all the target balls which locate upper side of the screen within 60 seconds. The number written at ball means bonus. It erases that numbers of balls (including the one collided, selection is random.) The balls at lower side of the screen give you penalty. If a ball hit a ball at lower side, the numbers of balls are added to upper side. If you finish erasing all the balls upper side, you win. In game over screen, the number at left upper corner means your actual taking time. Less time means you play better. If you take more than 60 seconds, Time over screen shows up. The other characteristics of this game is that a collision makes a beautiful explosion. The color is linked with a number written at ball. explosions are like fireworks. Please enjoy playing a ping pong along with fireworks!
