@@Ms.UmiValk yeah that one went right over your head lemme explain rq. Osu is older and more well known, but since i'm assuming you're not an adofai player, this map is basically the hardest map in the game. There are harder ones but this one is the most known and also possibly one of the most grindy in terms of time needed to put into it. So its more associated with with adofai because of how many top players try to play this map. (Think of it like osu!Standard's big black or freedom dive or image material or apparition basically)
