Wow, this was pretty grim.
Left me with a couple of questions: would I be into eating human flesh after 2 days (?) of no food? Probably not. Correct me f I'm wrong with the time gap.
Is it possible to not bleed to death if you've got a shirt as a tourniquet and you're self-amputating? I genuinely have no idea on this one. I guess it'd make a fair difference if it was above or below the knee.
Generally I was a bit unsatisfied with the ending but then, usually the ending is the hardest part to get right in a story.
Also, it was well within the protagonist's right to be stubborn, but I would've been pleading for mercy upon the first visit of the other guy, and then learning that he was asking about the woman, then be trying to strike a bargain to get a rope lowered and be pulled out of there.
Al's outro reminded me of:
