Hey cool game! The music is a bit much personally, I recommend a bit smoother sounds. It feels like my ears are being pierced by the music and sound fx lol. Otherwise the combat is fun and enjoyable.
So the music is pretty pixely, thats the best way to explain it. It was rough and every beat and bop was super hard to stand. I am mainly thinking that the pitch for every beat is too high. And it was all of the sounds. If your using unity there is a way to downscale the pitch in engine without having to go back and redo all the audio. Altho this method may reduce the quality of the audio and mood your trying to set.
