At first you have little idea what to do, but then certain steps become known and then quickly the solution. Spoiler I guided P and got pushed on R quickly after each other, skipping a loop. Also stepped on the slider from the other side, ditching R. But only B and P are needed at the end.
@Block builder - Yes that auto slider can provide a shorter method could also cause instability so I needed a stable method as well. Thanks for playing, commenting and rating.
I liked the level but dropped a star for instability. I thought i must be on the wrong gameplay as i was having so many restarts but determined to win with my gameplay anyway. So i was a bit surprised to see my win was so close to the designed win.
@ridgerunner - I just rewatched the video and I didn't see any instability at all? I do appreciate your persistence and sticking at it until you achieved the win. Thanks
