In this game, Alex Kidd discovers he is the prince of Radaxian, and his father, the king, has been kidnapped, allowing the tyrant Janken to claim power. The game details Alex's efforts to dethrone Janken (surprisingly, his father is not tracked down until a later game in the series).

Few other games allow mini-bosses to be defeated by playing rock-paper-scissors. In fact, the name "Janken" is a reference to rock-paper-scissors.

This is an improvement of 49.22 seconds over the previous run due to use of new routes, glitches, and other optimizations.
