Heyo guys, I've been playing Osu!mania for a few months and I think I've been stuck with just 3 stars or more that I can achieve B-S ranks but can't beat 4-star maps or at least have a B rank. I believe my fingers have reached their speed limit and wish to push the boundaries even more. The simple "Just play more" may not simply work on me. I make my fingers as close as to the keys to make the tapping instantaneous but I've seen other pro players tap their keys while their hands or fingers are hovering and despite that, they still beat 5 stars or above maps. I don't know how because I was amazed at it. Got any useful advice?
