Hi! Sorry for the very late response but the game is in total reconstruction.
The gameplay will be more focused on the number of Zeds the player could "collect" throughout the game, I'm now learning new skills in programing in order to have hundreds of zombies at the same time on screen with fluid framerate. And it's quite promising, I can go up to 500 so far, if I could go past the Thousands it will be insane!
The predicted release date is for Halloween 2019.
