I love it when villagers cheer for you when you accomplish something, it feels like you have your own personal cheer squad. It's so cute, and I'm glad it was added into the game. Did you know that villagers can wave at you too, like just not when you're exiting your house but also while you're outside too. I can't remember how to do it exactly, but i'm sure somebody here can explain it. It's a pretty neat feature and just makes the open world feel more alive.
I remember in WW you had to tap the lower screen, since the action happened there, but here it is by means of the megaphone. You just have to shout their name while you're not near them but they appear on screen, and they'll wave at you if they're on good terms with you.
