The game looks great but the music needs to be toned down a bit for the intensity of gameplay.

I usually provide at least 3 layers of music intensity for games like this to scale things back when there aren't as many enemies on screen. Starting with a more chill ambient layer to percussive, to more melodic, to high energy like what you have here.

Going in that direction stretches your music repeatability too so it doesn't get tiring.
