I really like the idea of the story. Someone who is nuts enough to go into a dungeon, where you have to sacrifice your own limbs, is cleary not the best person and the design shows that. I can see a lot of potential for a game where you have to sacrifice your colleges to keep pushing deeper, but also loosing unique skills from your colleges in the progress. Paired with some survival mechanic and we have a really good creepy, horror micromanagement game. I like that.
