Balls, as a rule, have a round shape, moreover, they are rubber or inflatable, which means they can bounce. All these qualities make it difficult for the ball to stay in one place. Tilt the plane slightly and it will already roll down, and make the tilt stronger and the ball on the bumps will begin to bounce. This happened to our hero, who was lying idle, and then rolled until he fell into an underground tunnel. Now, to get out of there, you need to get to the key. Help the ball in the Tunnel game safely squeeze through the narrow passages.
