Play Ninja Jajamaru - Ginga Daisakusen (Japan) [En by HTI v1.0] (~Ninja Jajamaru - Galactic Battle) Online

Ninja Jajamaru: Ginga Daisakusen came out for the Nintendo Entertainment System in 1987, developed by Jaleco. It's one of those lesser-known platformers from the era, a sequel that takes the series in a surprisingly sci-fi direction, swapping feudal Japan for outer space.

You control Jajamaru, a small ninja tasked with rescuing a princess from alien invaders. The game plays across single-screen stages where you jump between platforms, avoid enemies, and collect power-ups like shurikens and temporary invincibility. Each stage is self-contained, and you clear them one by one, facing a boss every few levels. The controls are a bit slippery, and the hit detection can be unforgiving, which gives the game a steep learning curve. It feels like a quirky, experimental take on the platform genre, mixing traditional ninja action with oddball space themes.
