Complete and utter garbage

this is my second game that i made prior to my first game made over a year ago (lost game). i made this game originally as a challenge with my friend and it still is lol, this is the only way for my friend to get this game lol.

this is probably the worst game ever as i have no idea on how to make npcs, inventories and health bars. theres no possible ways to damage the zombies, they just moonwalk and die, then they get revived?

enjoy this piece of shit lol.
