Don't expect a ball that bounces to bounce indefinitely. Sooner or later, he will pierce the platform he is on and fall into the abyss. Therefore, your task is to monitor the presence of nearby platforms and move the ball there while it is still balancing on the surface. You can make mistakes, but until you reach the finish line, you will not be able to move on. Practice, follow the trajectory of the jumper's ball and try not to allow unnecessary falls. Pass all the tests and finish with dignity.
