The intro cutscene blew me away, especially since the music has a John Carpenter feel to it. The setting and use of theme are spot on too. I especially like all the documents you can find, each one of them was an interesting read and made it worth the danger of finding them. As others have said the game seems overly punishing, currently, Maybe if you increased the visibility in the fog slightly, just so much that you can see shadows moving but still need to use the lamp.
I would love to see further into the game, I'm really interested in knowing the how the story plays out, it's just too hard for me to complete at the moment.
