Super Mario Bros.: The Lost Levels is a 1986 side-scrolling platform game developed and published by Nintendo as the first sequel to their 1985 bestseller Super Mario Bros. The games are similar in style and gameplay, apart from a steep increase in difficulty. Like the original, Mario or Luigi venture to rescue the Princess from Bowser. Unlike the original, the game has no two-player option and Luigi is differentiated from his twin plumber brother with reduced ground friction and increased jump height. The Lost Levels also introduces setbacks such as poison mushroom power-ups, counterproductive level warps, and mid-air wind gusts. The game has 32 levels across eight worlds, and five bonus worlds, each of which also has four levels.
