Fun little game! Very clean and enjoyable to move around the zombies. Clear and achievable goal. Balance felt impressively decent as I still would lose some zombies if being too loosey-goosey, but would get the satisfaction of taking over the base if I went with a bigger group. With a bit of expansion outside of the jam time, adding a bit more interactivity and further level design, I think this would prove to be a solid base. Great stuff!
