I've been told theres been issues with getting the rusty key to unlock the torture chamber door. It works fine for me, so I don't know what the problem is. If you have this problem, download it, and follow the directions in the "directions.txt" file, and your save game should have the door unlocked. (You might want to delete the save you have in there so the game only has one save to choose.)
the rusty key worked when i was playing it.
someone complained it didn't work for them, and I don't know how many people had that problem, so I'd like to give everyone the chance to get through the story.
