First I want to thank you for making a pretty in depth RPG that has some NSFW aspects built in. Now on to my suggestion and irritation.
The music is way to loud that is with me turning the music down to 20% in the options. I understand I can turn down my browser volume and actively do so but that means everything related to my browser also has it's volume reduced. The music is also so badly mixed that it being loud really shows how broken it is I end up turning it down to a minimum because the mixing literally hurts my ears and brain at the same time. I am a little loath to just turn it off though as you do change music based on scenes and am afraid to miss out on something good. I would like to point out that the mixing in the actual audio files isn't so bad, but how it gets played through the browser while actually running the game sounds terrible.
Upon further investigation the mixing of 'FantasyCinematic2.mp3' is actually terrible in browser or out. It is a very chaotic track and is also very muddy in the mix, one of the main offenders for grating on my ears and brain. The same can be said for 'Wheet.mp3'
Sorry if this is upsetting to read Airell, I'm just trying to provide feedback.
