Straight forward, easy level, easy herding. Need to be a little bit careful with B so he won't fall off the stairs or hit a ball too soon, and there's a little careful timing needed for the final move, or else P will get stuck on the pillar at the top of that lift instead of going where he's supposed to.
Good Level. Logic involved, but also requires care to not get into the critical places as described by @Sun Eagle and @D.S.Masters in their ratings, which, of course I did.
