Close call, managed to defeat the zombie horde with just one citizen remaining! (I may have accidently squished a couple)
Love the chaotic scenario of controlling the digger and accidentally knocking stuff over etc. Really fun! Cool that you mostly used physics objects (although I did stuck on a couple of things, like trees I think). Pathfinding works really nicely and the zombies made a very dynamic enemy! The citizens might have been a bit smarter and tried to avoid my digger!
Really like the lowpoly graphics, they suit the game perfectly. And you managed to create an impressively detailed little town, with multiple different access points for the zombies! It was very helpful that you included a minimap, though it would have been great if there was some kind of wave timer to show when the next wave of zombies was about to spawn (I had to wait probably about half a minute after the first wave and had started wondering if any more waves were going to come when they showed up). Sound effects were good, the game would be even better with some whacky music to fit the chaotic situation though!
