The background music is a lofi-horror synth track titled "Cauldron Boiler" by VVitchcult. It sounds like John Carpenter scoring a Halloween episode of a sitcom.
Remember, as Faust Seiker cautions, "The art of concocting Futa Concoction is not for the reckless or the faint of heart. Approach with caution, and respect the power of the unknown."
Sound design is provided by an anonymous synthwave artist known only as "Cemetery pH." The main theme, "Boiler of Souls," alternates between a seductive bass line and the screams of a thousand children trick-or-treating for gum. It is unsettling, sticky, and perfect for late-night playthroughs.
