About this game

A co-op version of Mario's Keep, a Super Mario Bros. puzzle ROM hack.

A side scrolling 2D platformer and first entry in the Super Mario franchise, Super Mario Bros. follows Italian plumber Mario as he treks across many levels of platforming challenges featuring hostile enemies to rescue Princess Peach from the evil king Bowser.

One day the kingdom of the peaceful mushroom people was invaded by the Koopa, a tribe of turtles famous for their black magic. The quiet, peace-loving Mushroom People were turned into mere stones, bricks and even field horsehair plants, and the Mushroom Kingdom fell into ruin. The only one who can undo the magic spell on the Mushroom People and return them to their normal selves is the Princess Toadstool, the daughter of the Mushroom King. Unfortunately, she is presently in the hands of Bowser, the King of the Koopa. Mario hears about the Mushroom People’s plight and sets out on a quest to free the Mushroom Princess from the evil Koopa and restore the fallen kingdom of the Mushroom People. You are Mario! It’s up to you to save the Mushroom People from the black magic of the Koopa!
