Sega忍者
Sega Ninja is an action arcade game released by Sega in 1985. Players control a ninja character navigating through multiple levels filled with enemies and obstacles. The game features side-scrolling gameplay where the player uses basic attacks to defeat adversaries while progressing rightward across each stage. Controls are straightforward, utilizing a joystick for movement and buttons for actions. The level structure presents sequential stages that increase in difficulty, with enemies becoming more aggressive and patterns more complex as players advance. The objective involves reaching the end of each level while managing limited resources and avoiding hazards.
