At least 3 ending, yup! And thanks for considering anyways 💖
One thing for sure now i'm inspired to watch not only Hazbin Hotel (already did both seasons) but the Hellua Boss too so good luck to me and good luck to you, may the goddess Fortuna herself shine a guiding light in your way the same way she does with me to find something like your project.
Also i would say a lot more about my theories but my perception is too much i think so i might accidentally spoil some plot to others without realizing it so probably shouldn't say too much of my ideas but at the same time i'm thrilled to know and theorize. I actually had the same urges with FNAF at the "good old times" so this project is really going under my skin the way i like it so continue on it it can go really far
