Richard/Jennifer has a similarity with Alyssa Hale and her male alter-ego Bates from Clock Tower II: The Struggle Within, as both characters were abused by insane fathers and suffer from a split personality disorder.
Richard/Jennifer can be heard humming "Top of the World (Two Hearts Never Lonely)", the game's main theme, when looking for Rosemary.
One of Jennifer's lines seems to be a reference to Dan Barrows' line "Let's play again Jennifer!".
When Jennifer is looking for Rosemary, she can be heard sing Butterfly (Farfallina), an Italian children's song.
Jennifer and Celeste are both voiced by Olivia Steele.
Richard Felton's first name is a contraction of Jennifer's second name : Richardine.
