I find levels like this a bit off putting. On first opening it looks chaotic and hard to see in the middle. I won using about half of the level.
I have now won using almost all the level . The only bit i am not using is the ball furthest away from B’s starting position . I am using claustrophobia to get B to the step. Pushing the ball stops that being possible.
@Steven Maki . All my wins were totally different as I never saw the passage used at 18 seconds into video. So i pushed B in the opposite direction at the start which opened up lots of different wins.
