I thought this idea was very cool and I liked switching between the different monkess, but having infinite amounts felt a little too easy. The theme felt slightly tacked on and I think could be improved if you had to go through each round in a cycle with limited amount of monkeys to place. I think not only could help with the challenge and strategy but it may also help lean into the theme a bit more. Sorry if im yappin, just thought the main mechanic was sick! Love the name as well!
