"Silhouette Mirage" was developed by Japanese video game developer Treasure, who had previously developed games such as "Mischief Makers" and "Gunstar Heroes". At the time the developer was shifting their focus to the Nintendo 64 and PlayStation, and announced that "Silhouette Mirage" would be their final game for the Sega Saturn. In actuality, Treasure would go on to make one further Saturn game, "Radiant Silvergun". Producer Koichi Kimura said that the goal of Treasure was to develop "fun games" and they pick the system that is best suited to the game rather than picking a system to develop for first.
