Nice variation on the push push type level. Had two wins, the longer of them looking like the designed win.
Not seeing it or B is doing it? Spoiler I see the mechanism goes back and forth one block. P walks up the stairs and with the next push gets stuck. I can see if B would go under the metal pillar, elevated eye may work but B will not go under? Edit - it's obviously the later as B has gone under at the other end but never at the required end????? EDIT - I'm done with it until I hear otherwise.
@gmacpro That's easy to move. Just push the platform with B from two sides, so P can reach the ball, timing needed. The title is hint to the last part of the level.
Nice puzzle with an interesting mechanism. However, before I found what must be the designed solution, Pillar-R managed to hit the win several times (even without pushing the ball) and I had to clue as to what actually happened except that B was wobbly.
