Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

Luigi has recently gotten into the renovation business, where he fixes up old decrepit buildings for some extra coins (using his previously learned building skills). He was checking out a very broken (and supposedly haunted) home late one night, where he found himself to be locked inside. Even worse, he left all his tools and equipment outside. Now all on his own, Luigi must traverse the 20 levels of this cursed house using only his wits and platforming skills. Bullet Bills, Ghostly Goombas, Dry Bones, Buzzy Beetles, and Hammer Bros infest the festering plot; now Luigi must dodge and defeat them all! With mushrooms, ice flowers, power stars, and major athleticism, this shouldn't be too bad, right?

This hack has many graphical edits, such as sprite edits, new color pallets, and new backgrounds. There is only 1 world with 20 levels in rapid succession, along with many secret warps along the way. Also implementing SMB2J Luigi physics for a fresh, more challenging experience. Plus some various changes to gameplay (like starting with 15 lives, for example).

Don't worry, it is beatable. ;)
