Super Mario Portable game
Super Mario World is a side-scrolling platformer. Like most games in the Mario series, the player plays as Mario (or Luigi by switching at the world map, though this does not affect the gameplay.) Levels are accessed through a world map; there are eight worlds, each containing several levels. The player moves through each level to reach its exit (some levels have secret exits) which unlocks a path to new levels. To complete levels, Mario must run, jump, swim, use warp pipes, collect coins (collecting 100 earns him an extra life), defeat enemies, navigate platforms, open doors, and avoid abyss, lava, and other hazards. There is also one level that takes place in a castle in each world, in which Mario fights the "Koopalings", who are the children of Bowser and serve as the boss for that world. The secret exits in some levels lead to one of five portals to "Star Road", an otherwise secret world; its levels are more difficult than those found in the rest of the game, but completing it is not necessary to complete the game.
