This really sounds like something that came out of a Geometry Dash level! The vocal chops really added to that mood, but also the song sounds very original from the actual pieces in the game. I liked the grainy intro, it really builds up to what happens later. The progression is very simple so it's even more impressive how you made it sound very nice! Keep up the amazing work :)
P.S. It's even more amazing that you did this in FL Mobile lol
