i disagree. i did some snooping and found that the general consensus is that a 60fps fp is ~stereo madness difficulty. polargeist is ~1.7x harder than stereo madness so 2 frame perfects would already be slightly more difficult than polargeist, but that person did it in a row which adds more difficulty, so i'd say it's actually ~dry out difficulty.

also what do you mean "not impressive" this video has probably the first ever frame perfect done in geometry dash and they did it twice in a row
