Alright, let's go with it. I'll drop some things, hopefully they'll be of use to you:
- Once you plant a flower, you can't pick it up again, so think carefully where you want them! Because if you make a mistake, that flower is forever lost. You can run over it to destroy it, but you can't have it back.
- Villagers will leave randomly without warning, and there's nothing you can do about it. They sometimes may mention that they're considering moving out, but it's just conversation, it doesn't actually trigger anything. Whether you say yes or no to them is irrelevant.
- Talk every day with the police dog outside, he will tell you when a special character is expected to show up in the next few days.
- Villagers will mainly be rude to you for some time until they actually warm up to you. Don't take it personally nor think there's something wrong with them, that will always happen at the beginning (but for a longer time in this game).
- Storage will be a problem. There's no inner storage in this game, and every wardrobe/closet/dresser can only keep three items each. So keep that in mind if you intend to hoard lots of things.
