Amazing atmosphere, music, and writing! The visuals added nicely to the atmosphere, too.
My main suggestion is that there needs to be better indication that you can interact with something. Even playing with sight, I couldn't tell what I could interact with, so I was just wandering around pressing A at random. A subtle sound effect to indicate that a piece of dialogue has finished would be nice, too.
I wish I had time to say more, but I'm rushing to rate as many entries as I can. Very nice work!
