DevelopmentThe game was originally envisioned for the PlayStation, but it was eventually moved to the Saturn.
MusicThe game music was done by the minimalist English composer Michael Nyman. The songs were recorded at the Abbey Road studio, known for The Beatles.
Special editionThere was an edition of the Saturn version limited to 20 copies that cost about 2,000 per piece. Although nothing was different about the release itself, it was hand-delivered by Kenji Eno at your home.
Voice actingJill Cunniff, singer/songwriter/bassist for the band Luscious Jackson provided the voice for Laura in the English versions. Since Laura remains mute throughout the game itself (as in D) you will only hear Jill's contributions in the brief "story so far" summary when loading your game from the voice recorder.
