I didn't use the last trick in your list but I can see where it would be used. Nice auto pilot move. Thanks
I used all the tricks but didn’t need the peripheral ball first time. The five stars is for the level when the shortcut is removed.
Wanted to get B on that higher walkway from the wrong side for some time. But then saw the solution, at first using the shortcut and skipping a ball. Enjoyable level with good design.
