Zombie apocalypse has been canned. I'm sorry. However, I'm remaking the game completely and giving it a different name. DEMO VERSIONS: 1.0 - Game released 1.1 - Forgot to add in the zombies back in and set the money to 0. UNFINISHED BUILD: - about the same as demo 1.1 but there's a health bar meant for the enemies. The shop is terribly bugged and there is mobile controls CANNED BUILD: - Only the color of the bullets were changed.
Thanks to @Warfame for the tutorial.
