Gunpei Yokoi
is a platform game developed and published for arcades by Nintendo in 1983. It was designed by Shigeru Miyamoto and Gunpei Yokoi, Nintendo's chief engineer. Italian-American plumber Mario and his brother Luigi exterminate creatures emerging from the sewers by knocking them upside-down and kicking them away. It is part of the "Mario" franchise, but originally began as a spin-off from the "Donkey Kong" series.
