You are playing as an Orange ball rolling around on a white platform. Swipe and Drag to push the ball around. Red and Green balls will fall from the sky on the platform, your goal is to push them off the platform into the matching colored orb. If you do that right, you'll get more health, if you make a mistake you'll loose health. Sometimes a Black ball might fall, it will throw you into the air if you touch it, so you gotta be creative about the ways you get rid of it. If the balls fall down but don't hit any orb, you will loose a smaller amount of health. If you wait for too long the balls will disappear and you will loose large amount of health. If your health goes to 0 or you fall off the platform - you will loose. But don't worry, you can always try again and again to have fun and try to score as many points as possible in this calming but challenging game.
