It isn't the whole map, it shows how some of the more weird puzzles work

That's only a single puzzle. It's the one that you went to after the museum room, and ended at that circle.

Yeah that is one of the infamous "developer rooms" which explain some of the goings-on behind the scenes.

WARNING: Shameless self promotion ahead!
I did a guide on how to get to all of these rooms, but don't watch if you are worried about spoilers of course :P
