This game has 12 character story modes each character's completed story unlocks another character and usually new game modes as well.
There are all kinds of unlockables and collectibles. Plus you get to learn about the different characters in the game. I had a hard time with the last levels of the 3rd and 4th characters, though. If you're good and puzzle/strategy games you shouldn't have much trouble. I liked this game alot. I hated it's predecessor Puzzle de Harvest Moon.
I love harvest moon games, and although this one was about farming it was nothing like a real harvest moon game. I played it for a couple of hours and was so bored with it. It reminded me of a bad farming version of tetris. They try to do a story mode but its not interesting and seemed very juvenile.
