15 years after the 3DO game release, the PSP remake with the same title was released. The main difference here is that live actors have all been removed, characters were replaced with silhouettes, and the game interface changed to look like a mystery visual novel but with selectable actions (such as talk or inquire). The latter of which makes the game less of a typical visual novel and only resembles it in its graphical presentation by using static backgrounds with dialogue text over it.
