No dogs jumping through windows...

I completed Amnesia (and the spiffy little Justine DLC), and I loved it! The game didn't make me go to bed with the lights on or anything, but I found it really intense. It was a nice change of pace to be helpless and have to hide in the face of danger, and to experience scares that didn't rely on surprise. I really dug the Lovecraftian themes and exploring the castle, but what really won me over was the balance of the gameplay; stay in the light or lose your sanity, hide from enemies in the dark, don't look at enemies for too long... Those design decisions force you to light rooms strategically, remember where you came from, and rely on the sound design. I highly recommend this one.
