Great job with the presentation, it really shined!
The game was a bit difficult. I didn't really understand how the different zombies/humans scaled. I had one human with a black shirt against one of my red zombies and they just fought forever until too many humans got into the line and just pushed through (without killing my zombies first).
But great take on the theme and really well executed! Very impressed that you managed to create this in just 48h, well done!
