This is a really neat idea and execution -- it really captures the experience of trying to navigate a parking garage if, like me, you have terrible spatial skills. :)
Interested to see if it develops further!
Thanks! No plans on developing this in particular but I think the implementation could be useful in a game with hand-made instead of procedural levels: a top-down 2D game where you could enter caves and go underground organically, or walk all the way up to the top of a long spiral staircase without changing screens.
