You couldn't just wander the rooms forever. You'd die. Eventually, maybe quickly. But you'd die. I get shades of this feeling in the Hebra Labyrinth, being hounded by a troop of Black Lizalfos and burning through my rations of cold-resist food. I get shades of it in the Lomei Labyrinth, sneaking past a Guardian in a claustrophobic corridor, risking a deadly game of Pac-Man should I wake it up.
