The greatest flash game every made.
Much like Tuper Tario Bros, this game needs to be stolen by Nintendo and made full scale.
IT's the complete AND ENTIRE Super mario Bros game, but you can play as Link, Samus, Megaman and Simon AND they play exactly as they do in their real games.
It's perfect, it even plays well with a controller (for those who know how to do that), for those without, keyboard (I used the crossed-hands technique).
Just utterly perfect.
