Hello!! Just a random suggestion, maybe try adding catchable diseases (whitecough, greencough, blackcough, etc.) and have each disease's survival rate increase/decrease depending on the experience level of the medicine cat(s). For med. cat experience, maybe they can have their own kind of patrols where they can do stuff like gather herbs for example. Im absolutely loving this game and have put multiple hours into it, and I'm very excited to see where you take it! <3
