Yes, thanks for noticing. I've been trying to improve my game jam music lately.
The best thing for music is probally the drums. Whenever I add then to the music, it seems to automaticly make it 20% better. Especially the chipnoise drums. Also both the bass and main instument need to sound good for the music to overall sound good. I've been praticing for a few months and my music only just starting to sound okay.
