Nice timing level. Spoiler: How i did it B stood near each stair to get ready, then stood in the ball. Thanks!
Balls goes too fas or too slow, that he cannot stand on it. Ok first can be controlled, but in second one, Ball stops under Stairs. Spoiler
I really like the mechanism that prevents the ball from falling if, after a complete cycle, the player forgot to lower down the slider. @Pratik Bhalerao It seemed to me that this was the purpose of the game : to send the ball not too fast and not too slow ?! + to jump in sync of course. Thx @trb
