If I lower my system volume, it lowers the volume of everything I've finely tuned so far.
And most of the stuff, like discords boops, and other such things, wouldn't be able to be heard,
due to how far down I'd have to turn down my volume;
it's currently at 25%, and the music from the game is near painful - not bad music, just very loud.
And I don't want to restart my game 20× or so until I have it at just the right volume.
This is unfriendly design. I don't think I'll be playing this game any time soon,
at least not until I have some way to access the same options on the title screen from within the game.
