UltraSonic by ZenthicAlpha | Road to 600 Demons | Geometry Dash
Last insane demon before non stop extremes. I'm really hoping I'll be able to beat the 7 before 2.2 or at least get to 599 so my 600th is whatever demon 2.2 has to offer.
Demon Rating: Insane Demon
Total Attempts: 4349 (probably 3000+ from a couple years ago)
