Super Mario Land is a 1989 platform game developed by Nintendo R&D1, the same team that designed the Game Boy. It was published by Nintendo as one of the first four games released for the console. It is the first handheld entry in the Super Mario series and the first mainline title not designed by series creator Shigeru Miyamoto. Modeled after Super Mario Bros. (1985), the game adapts side-scrolling gameplay for the Game Boy's smaller screen, with players guiding Mario through 12 levels to rescue Princess Daisy—in her debut appearance—from the alien Tatanga in the new setting of Sarasaland.
