I loved this game! Very fun, I was in the zone, loved insta-zombifying humans after I racked up a huge army of zombies, very satisfying gameplay, fun, catchy music and great SFX, what's there not to like! One of my favorite games that I've played so far in this game jam (I've played about 60). I managed to get to round 3 but the game crashed sadly.
If I could give a suggestion it would be maybe add a boss that appears after you rack up a huge army and try to fight it (idk if thats in the game already I didnt go that far), and maybe give the zombies more ways to attack! Good luck :D
