Ok, so I went a played it again. The music at the beginning is a banger, but by the time you get to the first groups of rogues and knights, the song ends and there's no more music. It doesn't loop or restart after some silence. The game is long enough that by the end I had forgotten there was music. I had also forgotten about the TV at the beginning. (I just adjusted my score for the music and theme up.)
For the SFX, they were fine when the music was going. When there's no music the incessant tromping of boots just got on my nerves. And the combat sounds seem to be at a lower volume level than the walking sounds, so in combat when troops are still moving, it felt hard to hear what's going on. Maybe that was intentional?
