I call this piece, Playful Alone. It’s the title theme of Harvest Island when you’re about to start a new game.
I named it playful alone because it’s a bit sad in the beginning but cheers up in the end. The theme is about what’s it like living on an island with just your family. The world is big and you have questions but no one can give you that. At the end of the piece, it becomes playful which resembles what it’s like to be a kid and you forget what your problems are.
