@delator77 What?! I don't even know how this works! Perhaps it was necessary to change the category. You win, if 2 times you drive on the valid Elevator after it first appearance.

@amber It's not most mind blowing. There's a lot of other tricks physics and mechanics, that you will learn. You can check this:
