"You would have prefer to be taller, or to have a rounder nose."
Okay, that really cracked me up.
That was a fun read, I liked the style. Very good job. As for the game, reading that made me think of Fallout 3 without the story parts. Lots of bugs which you can overlook and lots of looting and exploring.
The only thing that puts me off, which is true for most zombie games, is that I can't care for FPS melee combat. Other than that, it sounds interesting.
