Ninja Kun - Majou no Bouken
忍者君：魔城冒险
Ninja Kun - Majou no Bouken is a side-scrolling action game released by UPL in 1985 for the NES. Players control Ninja Kun as he fights through multiple stages to rescue Princess Kenju from the witch Majou. The gameplay combines platforming with combat mechanics, where players throw shuriken at enemies while navigating treacherous terrain filled with hazards and obstacles. Each level increases in difficulty and introduces new enemy types and environmental challenges. The game supports two-player gameplay, allowing friends to take turns. Control is straightforward: players move left and right, jump to avoid dangers and reach higher platforms, and throw projectiles to defeat enemies. With its fast-paced action and progressively challenging level design, the game demands both precision and quick reflexes from players.
