Its was an attempt
First of all, I got through the game with just the pistol, I didn't even lose any health. It was too easy, no ending scene or anything just your score, The guy looked just plain creepy SMILING all the time. When zombies attack I'm gonna be looking for the guy who is walking down the street smiling.
Anyways Good attempt, I'd love to see it untimed and survival with the ability to go into building, find other people and hold the building. Make it to where you need to find food and maybe gas for a generator and ammo. That would make a supurb game.
Oh yea a lil' "Shout out" to Pixilation: Apparently you've never played the game DOOM where it lets you hold over 200 shells in a shotgun
