I just wish it wasn't so loving weaboo, I have a roommate and I don't want anime girls all over my screen
Here's what you could do to fix that, in order of effort;
1. Turn your background dim to 100% (In the options menu)
2. Turn off combobursts (Also in the options menu)
3. Download a different skin (Plenty can be found
here)
4. Manually edit your skin's files out-of-game (File path:
user > AppData > Local > osu! > Skins >
name of skin)
I'm available if you need any help
