“So-so” The equivalent in my neck of the woods, is “not too bad” . But the level is much better than average. Provisional 4* as i have not used the complete level in my win for B which was straightforward logic without any tricks. I did not use the area of the zapper draggable.
I have found the full solution which is very good and close to 5*. Nice to discover the use for the ball. Shame about the obvious shortcut. Spoiler: shortcut Spoiler: full solution
I enjoyed the level so thanks for sharing. I did it like @ridgerunner's video so either you had some red herrings or I too found a shortcut.
Just like the others, I finished the level without using the zapper area in my first attempt. But I retried the level for the full gameplay experience. Good level overall, liked the level design.
The stability is so-so. Pretty nice level. Edit: my solution is not the same as in @ridgerunner’s video. I let B ride on top of P and the stack walked to the win.
