I don't know why this hasn't been addressed yet, but Bonnie's moan needs to be as loud as Chika's laugh. It gets completely drowned out by the music box and even the games music makes it incredibly hard to hear. On the flip side the jump scare's either need to have their volume reduced or give us a volume slider for them. They were so loud my ears almost started ringing from them, and I can't turn my headphones down because I need to be able to hear.
This is something both Scott Cawthon and all the fnaf fan game creators NEED to learn, don't force loud noises and potentially damaging peoples hearing JUST for some cheap jump scares. If you feel they need to be there then we need to have the option to lower them as much as we want.
