This was rather hard to play. Mechanic was creative though, it was fun to play and my only issue with that game was how there could be no zombies around and you would just run out of time. There is also a little problem on the 2nd map(forgot the name, its the one on the bottom) at a fence, where you can trick the zombies' nav to make them circle around the entire block to get you.
And also everything else, audio, graphics, aesthetic are amazing.
Great job!
