A Masterpiece
This is an amazing piece of work!
I especially liked how you had utilised imagination against us! Incredible use of technique like the way Alfred Hitchcock justifies things!
Graphics - very nice setting! (I'd like more detail, but that's just me, lol)
Style - yep, not gonna down you on this one! the setting really help set the mood!
Sound - Great use of sound! Although, you should include in the book "the first plays in my ears all the time now... when i wake, when i sleep, when i eat, when i breathe... it consumes the house" (Because I didn't really understand it until the explanation)
Violence -I should say it's practically none, but when immersed, the mind does the killing all by itself.
Interaction -Great interaction pieces! Here's a tip, next time add an animation to loop back to the room to stop r-clicking cheaters! lol, scare the clueless!! You could also create the intro... You know, just the rear view mirror and your char's mouth... Black and white for less definition to allow people to connect.
Humor -none, 'cept that it's cool. Need I say more?
Overall -Incredible. Plain incredible. Truely a masterpiece.
