Very cool offline multiplayer auto-battler mechanic! Love the little duck designs. I imagined they were all British so that I could get all my ducks in a row. The gameplay is also very dynamic. I had lots of setups that I thought were pretty indominable only to get trounced by someone's rock to my scissors. The random nature of the duck gacha means that you can't just run back whatever duck combo beat you. You really have to utilize the resources you have.
Great job!
