The story follows a boy and his pet dog as they are inadvertently transported to a fantasy world created by an eccentric inventor. The gameplay shares many similarities with Secret of Mana, such as real-time battles, a ring-shaped menu system, and the ability to switch control between the characters. The player guides both the boy and his shapeshifting dog through Evermore, a world that is composed of separate realms, each resembling a different period of real-world history. Control can be passed between the two characters at will; the player will need to switch between the boy and the dog in order to solve various puzzles.
