Nice take on the theme! It's a shame that I was the only one playing and I didn't find any players. I thought because it's an Io multiplayer there would be bots to play with, but I think that's a lot to ask for a game jam. I also don't understand why zombies are controlled with the arrow keys instead of following you. Besides that it's a pretty cool idea! I would love to see a game full of players. Good luck!
