34th

Spoiler

So many low ceiling moves i am not surprised i missed one at 1:40. I used an autopilot instead to get B across to the other side of the pushed ball. Rest of my gameplay was the same. Great fun.

@ridgerunner Thanks for playing and commenting. I love low ceiling. It is a trick so simple but with such a great usage. Good to know there isn't a huge shortcut in this level.
