> keep digging
Despite having lost all of your air, you keep digging in the sand, hoping to find the entrance through the Earth. You start turning red through loss of air.
> evolve gills
Congratulations! You've evolved gills! You can now breathe underwater with ease! You continue to dig under the water to find the entrance, but soon you get tired and choose to swim to the surface. Oddly, you cannot get out of the hole in the sand you have made. It is completely dark. The exit is now covered in hard, pointy rocks.
> examine rocks
They turn out to be the teeth of a Sand Grue. Of course, you know what happens next.
It appears that the last blow was too much for you. I'm afraid that you are dead.
As you take your last breath, you feel relieved of your burdens. The feeling passes as you find yourself before the gates of Hell, where the spirits jeer at you and deny you entry. Your senses are disturbed. The objects in the dungeon appear indistinct, bleached of color, even unreal.
> examine me
You appear to be made of a translucent floating white substance. There seems to be a golden halo hovering above your head.
