Building map

How this works: each room is drawn from its own tile data: a tile is walkable when the game's passability check lets you step off it in some direction, the same check the game runs when you walk. The pins are the room's events: the ones that hand out items, weapons or gear, the shops and what they sell, the doors to other rooms and the fights. An item marked under conditions is only given in some cases, such as after a story event or on one branch of a choice. Room names are the names the game's files use. Test rooms are left out.
