Alex Kidd in Miracle World DX is a remake of the classic side-scrolling platformer, sending the young hero Alex Kidd through colorful stages filled with enemies, vehicles, and rock-paper-scissors duels against bosses. Players run, jump, and punch their way toward rescuing his family and kingdom.

The remake refreshes the visuals and controls while keeping the original level layouts, and lets players switch back to the classic look at any time. It suits fans of retro platformers and Sega's early mascot era.
