COOL!
I know usually Mr.Game&Watch dose not animate that well, but I like the whole flash. Also just to let you know, Mr.Game&Watch has a white outline, he's not just all black. I also liked the way you made a family for Mr.Game&Watch. And there are some moves from Brawl used in here. Such as the pan of food, the Parachute, Even the smoke thingy, and the Final Smash (Except it's against him). It would actually be cool if he used the bucket of water to put out a fire. Also, it's not called Flatworld, it's called Flatzone. And also, the colour of the screen is usually Yellowish. But is was good overall.
