Best game on newgrounds in a LONG time
Well-balanced game.
Excellent graphics of gore was frosting on the cake.
As for having a positive ending on Day 20 - smart insight. Just because zombies are involved doesn't mean the world is over - afterall if Joe Blow can last 20 days an organized army can probably annihilate them.
The note by the page where you allocate your day-hours, as well as the diary. Those gave the game some humorous moments ("Call Mom If I Survive" -> zombie mom?)
