In the current version 0.4, when losing the final battle of the dungeon or retreating, when re-entering the dungeon, the group is thrown into a room with a final portal, when entering which the game displays the loss and the dungeon is not deleted, when re-entering the dungeon is reset, but even if you defeat the final pack of rats and re-enter the exit portal, the game always counts the defeat, so the dungeon cannot be removed from the map
