I don't know if this is just a me thing, but the volume of things with no focus mode active is too quiet, and too loud with one on. I'd like to see that adjusted a bit. Maybe by 5-20% or so.
The release I’m about to make addresses this. Doesn’t use your exact numbers, but I made non-focused asteroids a bit louder and focused asteroids a bit quieter. Let me know if that helps.
