Tbh I just tried it and it's extremely difficult. You can't predict what the ball will do it's ridiculously hard to control after you land and no youtube vid has someone that passed that last level in the vid you posted as well. The trailer shows a bunch of things but no one can get past that part, feels bad.

To make it worse, if you press escape, it says "game paused - resume - exit" Clicking on either or does nothing. At least I can alt + f4.

welcome!
