Who to save in super smash flash?
I'm presuming you mean super smash bros brawl. Super smash flash doesn't even EXIST! But anyway, the game will save automatically when you are playing normal brawls, and in the subspace emissary you can find certain save points that are behind the golden doors. There is also a save option on the main map there and it auto-saves every time you finish a stage.
Yes but in super smash flash 2,there are different characters like Sora,Tails,Goku,Ichigo,and more characters.Also there are different stages like a stage from Super Mario Galaxy and a stage from Dragon ball Z and more.And also the final balls are in the game super smash flash 2(but there will be all of the characters and stages in version 1.0)So Super smash flash 2 and Super smash bros brawl are 70% the same.
