I gave up quickly due to the hidden. EDIT - Turns out your hidden wasn't the greatest problem as when I returned, a mechanism finally moved to the win area. I attempted to get the timing but R kept walking back to R's starting position or kept getting off P depending which way I tried it so I gave up again for good.
Excellent and long clean logic/cooperation level...Very interesting and challenging path You only have 3 levels but all are really good so I want more Thanks for sharing @JTK
I ignored this level as the snapshot looked boring. But glad i eventually opened it , as it was very entertaining.
