The neon smiley ball is ready to run in the Physics Ball game. You will help him deftly jump along the lines-platforms, which become more dangerous with each level. The simplest obstacle is the empty spaces between the lines. Platforms are mobile, that is, jumping on it, you will provoke a slope. So you need to quickly jump to a more stable base. The finish line on each level is a green rectangle with a check mark inside. As soon as the ball stands next to it, you will be at the start of the next level in Physics Ball.
