I can't play this game anymore tonight. I just screamed loud enough to wake my girlfriend up. I'm posting this instead of going back to the game, because I'm certain that if I keep playing, I'm going to have trouble sleeping.

I've been through every Silent Hill, Siren, Resident Evil, and Clock Tower ever produced, but they don't have anything on Amnesia. It's by the guys who made the Penumbra games, it's twenty bucks on Steam and elsewhere, and anyone interested in having a game genuinely scare them should go buy it now.
