A small logic treat. To me this level would have been perfect if B was not allowed to step on pillarbot if pillarbot is on the stairs to the right of the ball in the screenshot (e.g. by placing something to the right of the horizontal metal pillar where pillarbot can still walk under). That would prevent the obvious path, forcing players to find the alternative. But despite the long description, it's only a detail. I like this level.
Oh I didn't see that shortcut... Anyway I tried to make it but it would have taken more space and the level would have been bigger
