I present to you, my orchestral cover of Dimrain47's "At the Speed of Light. Created with Musescore 4.
ATSOL for orchestra
Remix

At the Speed of Light gained a lot of fame in the (not rhythm) game Geometry Dash, being used in famous levels like Cataclysm, Bloodbath and Bloodlust. I really saw potential for a great orchestral cover. It is a bit slower than the original.
