Woo, good job! I don't think I'm very good at this one. It gets a bit tough when all the zombies start to converge on each other. My high score was just over 20. haha Pretty fun idea!
Thanks for giving it a go! Seems I accidentally created a built-in difficulty aspect where the player has to use the same finger to kick as they do to move, though that kind of makes sense when you consider how kicking works in real life. All planned, very intentional.
