Interesting idea! I like how quickly your horde can grow and you just start causing chaos. I only got to wave 4 so idk if theres any mechanics added later on but it would be nice to see some variety early on. It seemed like there were 2 types of humans but neither of them really ever got close to killing a zombie so it didnt feel like a threat. Maybe some new attacks to dodge like a gun or bomb enemy would be neat. Having some upgrades would be cool too. But obviously its a jam game so you can't add everything you want! Good job overall!
