This is really good for a fun casual game, i was gonna give suggestions to improve all the contestants games but yours doesn't need much. Maybe add a tiny variety to Zombies like changing some of their movement speed through RNG at the higher waves.

Nice, well good luck mate. Im not the judge guy but i have a feeling you'll win at this rate.
