Not a very productive day.

I managed to clean up some stuff I broke while making the A* hallways. To make those work, I had to change the definition of what was Passable in the grid from Floors, to empty space. Next, i changed the definition of Neighbors to only be the 4 cardinal directions since I don't really want diagonal corridors (they look weird).

All of this epically broke the Player's ability to actually move, so I did some refactoring to make those parts configurable, and now everything is working.

Better than nothing!
