Long ago, the natural world and the dream world were indistinguishable. But, due to people’s dark thoughts, the Nightmare was born and threatened to end the world. A brave sage appeared and sealed the Nightmare into the holy land using the Holy Instruments and the Dream Stone. The world has been divided into the natural world and the dream world. Years later, people had forgotten what had happened and only remembered it as a legend. Many people have also heard of the Dream Stone, which is kept in the Temple of Dreams. Enter Rumble, a Ruinseeker (a high-ranking treasure hunter), on a quest to find the Dream Stone. Simultaneously, in the Dreamworld, a Baku (a strange-looking animal that lives in the Dreamworld) named Tumble accidentally drops the box containing the seven keys to the Temple’s seal. The keys vanished and were discovered in various people’s dreams.
One must enter the plan and look for the keys to get them back. Tumble can join the programs, but there are many monsters and puzzles that he may need assistance with. Rumble realizes he needs the keys to find the Dream Stone. Rumble and Tumble decide to collaborate after learning they can help each other achieve their goals. Rumble and Tumble will travel around Sonno Island, meeting the people and looking for those whose dreams contain one of the seven keys in Dual Hearts. Each plan is unique, just as each person is, so the enemies and puzzles Rumble will face will be unique in each vision he visits. Everything in the Dreamworld is made of gold and gems, including the boss, who is a giant money bag. Rumble uses the Holy Instruments (a spear and a sword) to fight enemies in his dreams. The boom can use both weapons simultaneously, allowing him to perform a variety of combo attacks. Tumble will assist Rumble by carrying him on his back and allowing him to travel to higher planes. He can also perform various episodes, such as the Breath Attack. Our heroes must solve a variety of puzzles to progress. In one puzzle, for example, you’ll be presented with movable blocks, several switches, and a closed door. It would be best to determine which button opens the door and then move the block on the button. If you encounter difficulties, you can always seek advice from Tumble or the Dream Sheep.
