One Ball II

I am reluctant to go 5 stars as the ball wasn't stable for P to pass over and your trick list was incorrect. Please ensure your list is correct. I don't normally check hints unless I'm stuck but I do check trick lists to see what I'm up against. The logic in this level was very good to excellent so worthy of 5 stars.

one troublesome ball.
it feels like im playing a chess.
so difficult to figure out how to push ball
with the correct order which red bot
got frozen first and where to freeze.
one wrong step, restart!!!

very challenging to keep this ball
while pull metal half way to let B
doing claustrophobia

@Ray Aznable That move wasn't part of the gameplay. If P passed, The ball is not needed anymore.
