This Story is Going Nowhere Fast

You land, fortunately for you, unfortunately for Mr. Stiller, on his back. You are unharmed, but he is unconscious. You'd best get out of there before he awakens and unleashes his Stillerly wrath upon you for attacking him.

You look around. There seem to be some vines growing from the mouth of the sink-hole into the cavern. You also notice a cavernous path leading into darkness. There is a gun lying on the ground.
