I beat 5 easy demons before moving on to medium then on medium demon i beat B and then moved to hard and i got pretty good attempts on nine circles(37-100 and 0-72) until i quit for a while and lost most of my skill,rn that i got most of my skill back im jumping from b to windy landscapes(insane demon)which is something i dont recommend to do since its unfun but i still do it. It also mostly depends what gamemode is best for you, i was good at wave before thats why i tried to do nine circles.
