you need press the up arrow key to jump above obstacles. the goal is to get as much as civilians possible to make the biggest hoard ever. collect coins, and civilians, and avoid bombs. these can reduce the amount of zombies you have.
the zombies, civilians, coins, bombs, and road, and tunnel design are from me. I also used some code from Griffpatch`s tutorial on making classic scratch platformers. its not yet finished though. pls love and favorite.
