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.
First off, this game shouldn't even be called Harvest Moon. Sure, there's harvesting... in the form of a really annoying and superficial puzzle game. I'd like to say "give this game a rent to try it out", but then you'd be wasting your queue space for a game that might actually be worth trying out. Or wasting time playing it when you could be doing something more productive, such as counting your belly button lint.
Yeah, there are 12 characters you can play as (10 you have to unlock), but why you would want to is beyond me. My wife played this game and literally beat it in 15 minutes. No joke. I'd say that this game might appeal to 5 year-olds, but I think even 5 year-olds have better judgment than to sit through a mock-harvesting puzzle game even for the 10 - 15 minutes required to beat all the puzzles.
If you want to play a harvest moon game, play ANY of the other ones. Not this one. The only reason I give this game a 2 is because it isn't broken. Otherwise, this game belongs in the same landfill that ET: the video-game is now residing.
