To me it feels like a mix between chiptune music, both from early 80s and from the 90s, but also a more modern soundscape which makes it intriguing. I like the use of a theme coming back, but perhaps a bit more variation could have been in place (either in sound or the motif itself, or both). I also like how the theme was incorporated - You manage to both make it obvious and subtle at the same time - nice!
