If

I take it that B should fall off the tall stairs? My B isn't falling. What's the move?

Spoiler

ToA is needed?

@delator77 - That would help - let's see if you are right.... I think so.

I'm assuming the ToA was required to pass the stairs. If so then I rated the level as poor as it's a poor example of ToA. Albeit, you did have an ending to assist with the move but on the 2nd occurrence the move required numerous attempts on my device making for a very repetitive and frustrating move. The rest of the level was weak if you consider that this is a trick level.

This would have been a three-star level ... very average linear game play in a rather unremarkable setting ... pleasant enough until ... what? ToA? At the end of a flight of stairs? Twice? That was like telling an inspirational story of love and friendship, then ending with "and they all died in a car crash. The End."

Nice puzzle.

Ok. Thanks a lot
