The tunnel begins to get smaller as you follow it down. You eventually find yourself
having to hunch your back and bend your knees in order to continue forward.
It is silent now; the only noise is the sound of rocks crunching below your feet. There is no more light from the outside here.
The tunnel stops at a small hole in the wall. It leads into what could only be a deeper part of the cave.
Judging from the diameter, it will be tight, but you're sure you can fit.
