More hours have passed. What's the point in going any farther? I could be going farther away from my friends.

They could be a hundred miles way, in any direction, above or below! I can barely see anything. I stay still for an hour, maybe I'll hear something in the silence. But no.

I've been following the left hand wall as it twists and turns. Should I carry on? Or should I follow the right hand wall instead, and any tunnels on that side? I am so lost! Isn't there anything I can do?
