Super Mario Bros.
超级马里奥兄弟
Super Mario Bros., released by Nintendo in 1985, is a side-scrolling platformer featuring Mario navigating eight worlds to rescue Princess Peach. Each world contains multiple levels with progressively challenging obstacle courses. Players use directional controls and a jump button to move through stages, defeat enemies by jumping on them, and collect power-ups like Super Mushrooms that expand Mario's size and Fire Flowers that grant shooting ability. The game introduces varied enemy types and hazards across levels. Each level operates under a time limit. A two-player mode alternates turns between players controlling Mario and Luigi. The controls are responsive and precise, allowing players to master movement and jumping mechanics to progress through the increasingly demanding level designs.
