Not often does a FNAF fan game have an original score, but even rarer is when it's made by its creator. If it wasn't for the Faz project, it's unlikely that I would've ever had a reason to learn how to compose. But now that I can, this project can be given a tailor-made atmospheric soundtrack with proper lietmotifs and ambience.
Nothing too noteworthy has been developed other than the tones and sound, giving it a rich and depressing atmosphere that fits the story.
