MikuMikuMikuMiku by OddMod | Geometry Dash 

When I first saw this Hatsune Miku themed level, during the first half I expected it to just be an art level with a nice and soothing style, with a slow upbeat soundtrack as Accompaniment, but as soon as you get past the first minute, everything about the level changes, the speed, intensity, the design and even the music.
Seeing and hearing Hatsune Miku inside GD is surprising, and goes to show how popular this character still is, even after many, many years from it's beginnings as a vocaloid voice bank, to the icon it is today. The aesthetic this level has, it's pacing among other aspects fits perfectly with Miku, allowing for a nice variety in design and gameplay.
