Spelunker II is a platformer where you control a nameless spelunker tasked with defeating the evil demon Geyla, who has ruled Fairy Land for a thousand years. Your mission is to free the land from her grasp and uncover the secrets of the treasure hidden within mountain caves.
The game's gameplay revolves around side-scrolling action, as you navigate through forests, fields, and mountains, battling enemies, bosses, and overcoming obstacles like lava fields and pits. As you progress, your actions will influence the story, thanks to a unique Toku meter that tracks your motivation for saving the world versus collecting treasure.
