Moon Crystal

The gameplay involves 7 stages, each ending with a boss fight. As you progress through the game, you'll find power-ups that can help you, such as extending your knife range or giving extra health containers. You start with just a small knife to defend yourself, but Ricky can also make double jumps and more with power-ups. You have 3 lives and unlimited continues.

The game features fluid animations and rich graphic cut scenes that advance the story. Although it was never officially released outside of Japan, an unofficial English translation patch exists, making it possible for players to experience this action-packed adventure in any language.
