Cool game! I do think however if you could maybe add a refresher for some minigames that would be nice for new players or players who haven't played in a while. There are a lot of minigames and sometimes control schemes get forgotten, and so if you're playing a minigame where you have to do something you don't remember how to do, you're kind of screwed.
It would be very helpful for newer people like me who haven't played all of the games. I've only played the one on DS (and only a bit) so a lot of the minigames I have no idea how to play. Sometimes I know how to play but the controls aren't clear. I know how to play Fan Club, but literally have no idea what button is jump on the controller so I mess it up every time!
