> Crawl back against the door, then... follow the left wall! It might be a maze!

You crawl on your ass until you feel your back against the cold, metal door. You shiver a little. You use the handle to pull yourself up, your breath shaky and your legs feeling weak. For good measure, you jiggle it a little and confirm that it is indeed locked.

You start following the left side of a wall, making a mental map of the place as you do.

As you get closer and closer to the right side of the room (from the perspective of you with your back against the door, for clarity) the pungent smell gets worse and worse until your keen SCHNOZOMETER tells you you're right next to the source.
