Played around with a few prototypes for a game"loop" (heh) and finally settled on something I think will be fun to explore. Some rescaling and teleporting tricks to make it seem like the player is infinitely going through the same few rooms and will need to figure out how to escape.

Reminds me a lot of the Antichamber stairs, and I've always loved the idea of playing around with something like that.
