Before you is not a big maze, consisting of one long broken line. One fast ball can move along it, which you will control. The difficulty is that you will not be able to constantly hold the ball. To move it, you need to launch it into flight, like from a slingshot. Hop on a ricochet or try to catch the ball at the right moment and change its trajectory with a new throw. The choice of tactics is yours! The main thing is that in the end, he made the minimum number of impacts on the walls and achieved his goal. Good luck!
