Developed by Sega's AM2 Research Division as a technical showcase for the Sega Saturn, the game uses Japanese pop star Namie Amuro as subject and vehicle for demonstrating the hardware's capabilities: real-time rendering, lighting effects, and texture mapping. As a rhythm game it gives players a direct interface with the performance — but its primary purpose, visible in every visual effect, is to show what the Saturn's engine could do at the edge of its technical range.
