Alex Kidd in the Enchanted Castle description
This is a first real sequel to Miracle World.

This is a first real sequel to Miracle World.

The mission this time is to rescue Alex's dad, who's gone missing in the land of Paperock. The name of Paperock comes from the game that every citizen likes to play and is an expert at: paper-rock-scissors, also known as Janken in the civilized world.

You've got to guide little Alex through ten stages of punching, jumping and kicking, and Jankening, to gain passage to the Enchanted Castle, where you will do battle with Ashra and hopefully rescue your father.
