Thanks for playing and for the review! It's clear that the difficulty needs some tweaking (I'm not sure anyone has beat it yet -- besides me haha). And yes, all the music is original by me. Glad you liked it.
I'm planning on making some balance adjustment based on reviews after the competition is over -- better telegraphing boss attacks, lowering damage output and hp a bit, and reviews like yours help me get a sense of what to adjust. Thanks!
