Geometry Dash: Arctic Lights by Metalface221! (EXTREME DEMON)
First to beat. This is absolutely insane, I never would have expected to even play this in the first place, but once I missed a legacy demon (being twisted tranquilty), I knew I had to unleash my rage on something lmao. About the level, this was actually incredibly well made and balanced, and was really fun to play throughout the entirety of the journey, which doesn't happen often. As for the difficulty, its definitely harder than plasma pulse finale, but and also much easier than Tartarus so frankly I have no clue where this would place on the demons list, except for above ppf.
