Done. I've rounded the walls and put lights near the exits (which means they're now 2-tile large instead of 3-tile). I "created" 3 new tiles for the flipped walls, it's not spectacular at all but it does mean I have to export the tileset too. Also, the NPCs in the central hut are stuck in the solid tiles, this has to be fixed but I leave it to you since I'm not sure my ROM was up to date as for the events.
Finally, notice the crab in the central hut, it's made up of tiles of meat and tiger carpet
