Nice clean level. I didn't like the up the stairs to drop a ball - for some reason, my B needs 3 or 4 attempts to drop a ball up stairs. I also found the hidden center hard to see and to know what would happen (where are the routes). I found a shortcut at 2:52. As P walked away, B landed on the path and went directly to the brick instead of taking the scenic route.
Spoiler: Shortcut The first ball destabilized P, who dropped off the ledge into the water with B riding on top. As P righted himself, he made the column fall and B walked right over it to the win!
@Don G Rowe thank you for pointing it out, but I think you need a bit of luck too, I've tried a few times and I've never been able to do it
@Andrea gerbillo Oh I'm pretty sure the only reason it happened is because I wasn't trying to do it! But I have been able to replicate it once intentionally. Not a huge issue. It's probably random enough to not have to worry about fixing.
