Super Mario Bros. Crossover

About

Super Mario Bros. Crossover is a fan-made platformer that swaps Mario for characters from other classic NES titles. You'll jump, run, and battle through levels inspired by the original Super Mario Bros., but with a twist, control icons like Bill Rizer from Contra or Simon Belmont from Castlevania. The gameplay sticks close to the formula that made the 8-bit era iconic, with precise controls and challenging stages. Each character has distinct abilities that change how you approach obstacles and enemies, adding variety to the familiar formula. The game’s charm lies in its roster of non-Mario heroes, offering a nostalgic nod to other Nintendo classics. Though it launched in 2010, updates continued through 2013, refining mechanics and adding content. Community feedback often highlights the difficulty spike in later levels, which can frustrate newcomers. Still, it remains a polished love letter to NES-era design, best played with patience and a fondness for retro challenges. The browser format keeps it easy to pick up, though the lack of modern comforts like save points might feel harsh.
