Sephiroth Ultra by Soup26 - 100% (Insane Demon)
Update: Somehow the level got rated, not only that but it's an extreme demon?? So I guess this would be my first extreme under 500 attempts. It'll most definitely get rated down soon though.
Update: Back to insane
Pretty fun, didn't care much for some of the microclicks in the dual though.
thanks to geometry dash extravagon for showing me the level exists
