@Lenny Busker Spoiler: hint 1.when starting, quickly drag the draggables up and make B onto the draggables. 2.make R down.
I came here to see if there were any hints and it turns out that I was starting out right but with a mouse and more than 20 attempts - B was still stuck. Definitely not a fan of 0 seconds starts.
@Mike_CN Hint. I don’t think many people will find your clue two helpful. Spoiler: Clue 2 i contrived to make B bend over so P will walk onto him. There are at least two ways to accomplish this.
