I'm here after the jam finished, checking out some of the top submissions to see if I can learn something from them. I think your song is great :). It is relatively simple, great to be in the background of a boss fight, but very well-executed. It got few but powerful chord progressions, a nice brass section, a pleasant-sounding synths, a good rhythm and a strong beat. And I love the bubbly sound - did you use some form of synth or a sound effect for that? Overall, I like having this song on repeat, well done!
