I do absolutely love the idea of this; however, the limit of five mini-games was a little unexpected. I went into this expecting a sort of Wario-Ware kind of thing.
That's not to say I dislike this by any means– just that my personal enjoyment was hampered by my expectations being fundamentally different from what the game actually was and is.
Again, not a "game bad unga bunga need fast minigame" kind of complaint– actually this isn't much of a complaint at all, because the minigames you DO have have enough variation to them that they could easily be entire games of their own– just a personal opinion typea deal.
