Ninja-kun: Majou no Bōken

Ninja-kun: Majou no Bōken features three upward scrolling levels that repeat and become more difficult.[1] The objective is to defeat the enemies on each screen and advance to the next screen. The player can attack with shurikens and jump on enemies' heads to stun them. Occasionally, an orb will appear and if the player collects three, a bonus level will be unlocked.
