This is the most famous game in the Alex Kidd series, due in no small part to frequently being bundled with the Master System (and being built in to some versions of the console).

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 02:41.47 over the previous run due to the use of new glitches, and other optimizations.
