To the left.

Left of course, going left had never failed you before so why would it now?

You enter into a chamber, much the same as the one you started in. Similar size and similar shape, however in this room there was only on path that branched off. This registered secondary to you, because despite your urgency to find an exit you can't help but notice a faint outline towards the back of the room.

The object seemed to be rectangular in shape, dense, and centered on the back wall. The object was further into the room, past the open entrance to a further hallway.

You could continue on, making use of your time and energy, only focusing on drudging forward and finding and exit. You could also go investigate the outlined object, it could be survival gear from past explorers; or it could be better clothing. The frigid air is making you develop goosebumps, you feel your nipples harden against the cool breeze, the rough fabric of your shirt distracting you more than you'd like.
