Super Mario Bros is a platform game developed by Nintendo in 1985 and published for the Nintendo Entertainment System.
We take on the role of Mario, a diminutive mustached man wearing red overalls over a brown shirt, or in the case of a second player, Luigi, Mario's younger brother, a similarly mustached man wearing white overalls over a green shirt.
Our objective is to race through the Mushroom Kingdom, evade or eliminate Bowser's forces and save Princess Toadstool. Mario or Luigi can be hurt if either touches an enemy. If he takes a hit as regular Mario, falls down a pit (regardless of status), or the time clock runs out, he loses a life and starts again.
At the end of each worl, we will meet Bowser the boss. Bowser may be defeated in one of two ways, either by touching the axe at the edge of the bridge or, as Fire Mario or Luigi, throwing fireballs at him to defeat him directly.
