    Alex Kidd in Shinobi World is a side-scrolling platformer game with a ninja theme, with Sega transplanting their erstwhile mascot in their Shinobi world of masked assassins. The gameplay is a crossover hybrid of Alex Kidd and Shinobi. In particular, it is an Alex Kidd style parody of the original Shinobi.

    It was the final game to feature Alex Kidd in a starring role, though he would continue to appear in Sega properties in various cameo roles. The game was developed in Japan but would not be released there: Sega had ceased production of the Sega Master System console in their native land in favor of the Sega Mega Drive (Genesis). Instead, the game was localized for international audiences.


    Alex Kidd was having the time of his life, spending a lovely afternoon with his girlfriend on the planet Shinobi. Suddenly the sky was covered with grey clouds and after a flash of lighting a dark figure descended. This figure then grabbed Alex Kidd's girlfriend and then disappeared into thin air.

    Before Alex Kidd could figure out what happened, there was another flash of lighting. This time a White Ninja appeared before him. Alex Kidd looked up as the White Ninja spoke.

    "The wicked Dark Ninja, whom I banished ten thousand years ago, has returned. He took your girlfriend hostage, in hope of taking control of the Miracle World. I have come to give you my special Ninja Power. Use it wisely to exterminate the Dark Ninja!"

    The White Ninja threw a glowing white ball to Alex Kidd and disappeared. The ball filled Alex Kidd with an immense amount of strength and courage. With this Alex Kidd is ready to defeat the Dark Ninja and save his girlfriend.


    Alex Kidd in Shinobi World's most original gameplay mechanic is the wall-to-wall jump, which it was the first known game to use. Building on the basic wall jump in the Sega Master System version of Rastan, Alex Kidd in Shinobi allowed Alex Kidd to jump between walls, as a way of climbing up levels. It required precise timing, adding an element of challenge to the game. This mechanic would later be used in the Sega Master System version of Ninja Gaiden, Super Mario 64, and the 3D Ninja Gaiden titles, among other games.
