Super Mario Bros. is one of the best known Nintendo titles that was originally released on the NES. Released in 1985, it follows the story of Mario, who needs to rescue Princess Peach from the clutches of Bowser. It takes place across 8 worlds of increasingly difficult gameplay, each containing 4 levels.
Brandon, however, aims to rescue the princess in as few presses as possible, and does so in 142 total.
