Calico is 100% adorable - I love the characters and the animals are all so sweet! I'm enjoying the quests and learning everyone's personalities too.
I would appreciate a quick travel mode though, because it feels like I spend more time going between people for quests that speaking to them sometimes - but maybe that's just because I haven't unlocked flying yet.
A bug that I've noticed in my game, is that the fox, polar bear and shiba all run back to the cafe as soon as I stop riding them.
