About Ninja-kun: Majou no Bouken

Arcade port of the first game in the "Ninja-kun" series. You control a little ninja who has to defeat each enemy on screen. The game's formula is reminiscent of many other games of its time. You have very few stages packed with enemies. Once you have cleared all stages the game repeats itself just with more and deadlier enemies. Graphics are basic and the sound and music are annoying. It is a bit beyond me why this game started a successful series...
