A New Ending

As the walls are closeing in, there is no time to panic. Think, think, think. The walls are closing directly over the pit. How deep is this pit? As I inch my way tword the pit, I search the wall. Iron walls of heat bearing down on me, but how are they heated? Reaching the pit I lean over and can see nothing but darkness! There is no time to waste. Leaning down I near the wall to the right and by reaching my hand into the pit and under the closing wall, I pray to not burn myself. Reaching far and around the underside of the wall I frantically feel for a notch in the other side. I feel none, but how is this wall heated? There! A tube is hanging a few inches up, but I have no time to question anymore! I grab it and jump into the pit, hoping this tube can hold me. Yet, it is a flimsy material. It snaps when holding my weight, and i am falling...falling...fallling.
