You definitely have some great graphics, and so far your game is the only one with audio in it, so it has a great atmosphere that makes it rise above the rest. Unfortunately, I have no idea what I'm doing or where I'm going. Looking through you slides, it looks like there are a lot of rooms that look exactly like one another, and I got to say that's pretty bad design. Each room needs to be unique, otherwise the player will quickly get lost. Even something small like adding a candelabra or changing the camera angle would help the player orient themselves better - "have I passed through this room before? No, that had a sconce in it and this one has a set of armor."
