OK try to make sure that they can send messages to faraway villagers in a way... maybe by a pattern minigame!A bright one
could say "I'm happy" A black one with a yellow 'window' could
say "I'm scared" or "help me" and a bright green and blue pattern
could say "Meet me" Yeah,that would be cool.
I also like things that encourage them,like food,glorious food!
I wish something else would make them happy.
