I love it! Nothing is better to read about then zombies...i hope you write more storys like this.

It's very atmospheric, although you could have developed Mort a bit more. I call him Mort. Y'know, MORTem? It's a dumb play on words. Well, you didn't give him a name. You took everything else away from him, you couldn't even give him a name? A CEO?

Nice work. You described everything well without it being TOO terribly gory. It was so creepy, I loved it.

awesome story. i never thought about how zombies really felt... okay i must sound really stupid, but this story's great.

Been reading too much Twilight, eh?
Despite the disturbing scenes, it was well written, you built a strong image in my mind. I could picture everything clearly because it wasn't confusing.
The only criticism is that at the start, i felt sorry for the main character but then in the end he was the enemy. In my opinion, i think it would've been better if throughout the whole story, i felt one emotion towards the character, from the start of the story to the end.
So the reader might hate or love the main character but this should be maintained throughout, unless there is a major twist, where the good guys turns out to be evil.
I hope that makes sense. Over all, a dark story with a humorous touch to it.
Well Done!
