The Door Closing sound effect is a descending scale of notes that was probably supposed to be played when Rosella closed a door, but in game, the doors are closed automatically behind Rosella. There is only one door in the game that Rosella can close, and that's the crypt, but when she closes the crypt, the Door Opening sound is played. The jingle song was composed by William Goldstein.
