So simple yet so great. I wish there would be an option where i could add .mp3 and set a nice 2hour Berlin techno set in the background or an option where you are able to set the background music loudness. It would make it fuckin immersive.
If you have the patience to make a mod you can make one that does just that. I made a mod loader here: https://github.com/AGO061/BuckshotRouletteModLoader
(putting it here just in case you really want to)
