A colored ball jumps from wall to wall. In order for him to hold out as long as possible, he needs to beat exclusively on the surface of his color. Each time during the collision, the color of both it and the wall will change. From time to time, obstacles will appear on the playing field that can knock him off the field. Beware of them and try not to fly out of the surface. Hold on as long as possible. And, if you want to set a new record, then collect as many crystals as possible. Good luck!
