A somewhat messy and random move costs 1 star, but pretty fun once you realize that the move is intended and not a shortcut.
Funny and challenging step. Could manage two different steps. One on the ball, the other behind the ball. Spoiler: Poor B will be squeezed anyway
There's one interesting logical step, but I don't think the level offers more than that. The design is purely functional, and the rest of the gameplay is filler. Ok filler, but still filler.
