NINE CIRCLES 100% (Hard Demon) by Zobros.

I beat this level like 3 weeks agora, and it is my 4th hardest completion in the game. I would recomend Nine Circles as a first hard demon, because it improves your wave skills a lot. But my enjoyment is a little low, because I struggled with it a lot on the beginning. But when i got to 120 fps, i beat it in 30 minutes, só my ratinho will be 7.5/10.
