The Graphics weren't the best but the game play was addictive. I like the various defenses. But you should remake this and work on the graphics maybe add a weapon or two. The upgrades helped alot although I never used my grenades, It gets a bit repeditive after the 10th or so continue oh and the various zombies were brilliant My personal favorite was the Headless Zombie. It takes 2 fully upgrade shots to kill it.
