Baldren (who can be renamed by the player) finds himself warped and stranded on the land called Rainbow Moon, opening the portal to various monsters who swarmed into this once lush and peaceful land. The residents of the land do not discriminate him or the monsters, so he needs to earn their trust and prove he's not just another badguy invading their territory, and that can be done by helping them with various tasks and quests, all the way while looking for a way to seal the portal and return to his home planet.
This game uses isometric graphic during both exploration and combat. While exploration is done in real-time, until you engage in dialogue with an NPC or start the combat encounter, the battle is turn-based and lets you do typical actions found in such role-playing games, meaning attack, defend, move, use item or magic, or try to flee the battle which may cost you some of the experience points. By solving quests and defeating monsters, your character levels up and earns experience. Monsters often leave items and gold behind which can be used to trade in town for weapons and other goods. Map of the area can be checked while exploring the lands, and auto-mapping feature takes care of displaying all the objects and areas you have uncovered thus far.
