Always cool to hear someone record their music live! I like how you leaned into the imperfections of the recording, it gave the soundtrack a unique texture. You also took a really cool direction with the theme here.
One thing I'll point out is the battle theme feels like it just fizzles out, rather than coming to a proper conclusion. I'm not sure if that's because of the time limit or not, and I'm not sure how I'd fix that, but it might be something to think about next time.
