Moon Crystal (ムーンクリスタル), a platformer only released in Japan, follows a boy through his quest to save his family. The mechanics of the game are slightly reminiscent of Ninja Gaiden and Prince of Persia, with rather detailed animation.

Items that can be obtained include boots which allow a double-jump maneuver, and a sword, which causes multiple hits when the character's energy is low. Bosses are defeated quickly by using this sword power-up, after taking enough damage to activate its extra power.
