Alright, I gave the teaser a shot. As far as the gore goes, what I've seen so far hasn't really bothered me, and the story was compelling enough to get me to wanna play more. Unfortunately I think I triggered a bug that prevents the elevator from going back down into B2:
I rode it back up to B1 after picking up a key to the right of B2 and getting chased by skeletons(?) because I wanted to save and not repeat the riddle scene after every death. But when I tried to go back down the elevator seems to get stuck in a loop where it appears to constantly descend, and when I try to leave it just puts me back into B1.
