I've been thinking about how osu! would look like in vr glasses if there was such a function. I'm not an advanced user, I just got my first 86pp recently, so do not hate me pls if there is any topic like this.
There already exists an application on Steam that allows you to play osu in VR and with some extra features. It is called McOsu but I have never tried it so I cannot tell you if it is any good or not and you can't submit your scores using this application but you should still try it out.
