That was... fun??
At first I though it was crap. Crap crap crap. Then after the instructions went away, I waited a few seconds for the enemies to come. Crap crap crap. 3 zombies started chasing me. Try try try. At the end of my 470 score game, there were over 13 zombies chasing me around the screen!! FUN FUN FUN!!!
For once in my sad sorry life, I accualy see a 3rd person shooter with an accualy CRITICAL use of the jump shoot. It also aimed nearly completely downwards, which proved very usefull with a crowd of zombies surrounding me. Also, the simple controls make the game very easy to learn and replaying it brings all the more fun. You have amazing gifts for making fun simple games that the stupid people who vote 3 on Final Fantasy A+ try to blam this. Making a Zombie Grounds X SE or something with better graphics and a bigger map and upgrades, such as buyable things at the end of each level might be too much for you, but work at it if possible in the future. Definetly a contender for front page.
This is a great submission, and it's going into my favorites.
