I think we have a winner! :) This game is freaking AWESOME. That's the best use of shadow casting I've ever bloody seen :D
I love the art, the music, the sounds, the constantly increasing tension (even though I'm not a horror fan in general)... it's all very polished and well balanced. Reminded me a tad bit of 5 Days a Stranger by Ben Croshaw, I might have to replay it soon ;)
The only thing that could make this game even better is multiplayer!
