Jet Lag by disp (First Platformer Demon) | Geometry Dash 2.2
Platformer demons are gonna be very interesting. On one hand this level was very challenging but on the other it only took me 20 minutes. So although it was like hard demon-ish difficulty it didn't take a ton of effort. So I would kind of agree that it is a medium demon in terms of time but definitely hard-insane in difficulty
