Very tense.
This is the first time I've finished this game.
I played the second make first, and it was just as well done.
The graphics were simply amazing, and the sound just set the mood. There was no need really for music or anything. The fact that it was almost completely quiet made it even more creepy.
Also, I have absolutely no idea what the thing was in the hallway, but it just randomly showed up out of nowhere and scared the shit out of me.
A very tense game...
The only reason for the humor rating was because of the head in the microwave. :] The concept of a head in a microwave is just funny.
I can't wait for the third.
