Got off my fat ass and finished the code for having multiple levels in an area, with a 2d map for each, and correct numbering schema for displaying ground level, levels 2-5, and B2-5. Also updated all the inter-area loading screens with small area flavor titles, so It's not just Dungeon:Area1:level w/e.
Think I was doing most of this as an avoidant behavior because I have to update the quest system to a data table and refactor around it.
That's the last pillar system to unfuck before I jump into content generation for a finished demo though, so that's nice.
