This version is much better and I like that you gave B a chance to either go over the top or use the stairs if B fell. Nice ball trick too. Thanks BTW, if members use the auto pilot trick and they will, there's a few shortcuts. Spoiler: Shortcut Since the slider that goes to the win is only one block high, B can climb up with the auto pilot trick and get to the win.
A fun parcours with good ideas, mechanics, appealing design and not too complicated ...thanks for sharing! ;0)
