Tough one to rate as it had excellent potential. I'll need to know how B was to get on the zapper side to redirect P. I did it like this but it wasn't very stable and required a lot of attempts. Spoiler I auto piloted off off P onto the stone block and mid air tapped onto the grass. Since P was there, I often got a circle tap but B wouldn't go or B fell off the level.
@Meko Guy Spoiler 1) B drops a ball below the vertical slider 2) lift up the slider and B could walk past the slider.
I didn't win as intended but I won without using any of the balls. Nice level that was hard to read. My levels are easy compared to this one.
