Empty Building

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

Aesthetically pleasing. Good logic. Some sneaky stuff going on in this empty building!!!

I ignored this level as the snapshot looked boring. But glad i eventually opened it , as it was very entertaining.
