Honestly, I'm not typically a fan of Zombie games, because I don't care much for "spooky"/horror zombies, but this was really cute and enjoyable. While "trying to make humans become Zombies" isn't a unique concept, having them as a means to "platform as a hoard" is something that I haven't seen like this before, and it's surprisingly fun!
I'd definitely be interested to seeing more levels if you decide to make a post-jam update!
