As you play, you'll notice that the game has this amazing core loop where you're constantly collecting resources, upgrading your tools, and unlocking new things. It's so satisfying to clear out a new area of your farm or catch a rare fish. And, let's be real, it's pretty funny when you accidentally befriend a random villager who becomes obsessed with you.
Now, about Leah - she's one of the villagers you'll meet, and she lives in a cozy little cabin in the woods. You'll have to build a relationship with her, which is a big part of the game. It's really cool how you can give her gifts and talk to her to learn more about her story.
