Where this comes from
Every room, passage, mirror, pickup and name is read from the game's own files and drawn in the style of the in-game map.
Heart fragments, chests and Mammon's altar eyes sit on their exact spot. When a room has one chest and one item, the item is shown on that chest. What each Brave fragment needs comes from a guide video's on-screen cards. Other pickups sit in the middle of their room for now.
