Most polished art I've seen so far in the jam, and a pretty addictive gameplay loop.
I found it pretty easy, since the more one-sidedly you win, the more upgrades you can buy to win even more one-sidedly in later rounds. But that's just how this genre goes.
The round with over 1000 toddlers was hilarious and lagged the heck out of my computer, then the game crashed on round 56.
