After playing @D.S.Masters "Sultans of Swing", I said to myself, "You know, that swing looks ... useful." No tricks needed to reach the exit.
Very straight forward level. The hardest part was herding R back after dropping the R ball but hard is not the right word.
That was fun, ! Nothing difficult, but some unusual features. I was glad of the recovery stairs when B went flying, because I was a bit clumsy with that swing sometimes, !
Thanks for the shout-out. And yeah, nicely useful - and amazingly enough, I didn't Bullwinkle B off the level, though I did lose that ball that R hits the first time; after that it was smooth sailing. I don't know if dropping R off the swing is the proper method after he hits that ball, but it worked for me.
