Wow. The subject matter is very dark in a way I didn't think was possible. The decisions I made felt like they had weight, and as the story progressed I was drawn into it more and more.
With just a bit of polish (sprite resizing, adjusting camera angles, pulling back on walking and chain shaking sound effects) this could enhance the game beyond great and into best, IMO.
I really appreciated the movie reference too, as a fellow fan of classic horror.
