Wario Ware: how long is it

[Voltun]

I got Wario Ware as a present, and it seems kinda short. Is there just the map of that one area. I've beaten all the story things on it. Are there other maps, or is this it?

I think if you play the ones already completed & get by the boss stage i think you move up a level. Certainly did with me on tiny wario stage.
