(no surprise that you don't like mainstream services since you use linux (don't worry I use linux too (even if I use Windows when I make music because making music on linux is a hellhole)))
The first track dragged on for too long honestly, it could be cut down to half it's time. I liked Dystopia's bass, but there are also some parts where it's a bit too abrasive for me. I liked the panning on "Underground". Still, the soundtrack is quite original since it's "real" chiptune, which is nice.
