Kid Niki - Radical Ninja (World) — About this game
Kid Niki: Radical Ninja uses a spinning sword to cut through the enemies between the ninja and the kidnapped princess. The circular strike covers a small space above and below the blade, while jumps carry the hero across pits and other hazards. Bell pickups temporarily add protection or offensive support, but the ordinary hero cannot absorb an enemy hit. Boss encounters ask for several successful strikes against a pattern or weak point. Learn the sword’s distance before jumping into another group, then watch the boss’s response after the first hit instead of continuing forward blindly.
