Yes not many people know about it but I really enjoyed it, it's one of the better games I've played and the custom stories are quite fun also(some are laggy with some glitches). But you should really finish Amnesia: The Dark Descent, the last section of the game is really the most exciting part, which chapter/part did you finish last?Not many people know about it. I still have to finish it!
Ah your actually not far from the end, a little more than 3/4 a way through best of luck, remember to watch your corners lol.I think I'm at a section which is basically a 4-path X shape, floating in the air.
