Yeah, I had to do all songs in like 2 hours in last day, last few weeks I started to look into music stuff and "analyze" the music I like to see how to make something xD
I used to do worse stuff and a few days before the last day I still struggle with how to mesh instruments until I put more attention to some songs and I could come up with something, still missing theory and more, in the middle part of the boss song, the idea gets "muddy" because I don't know how to define some progressions but yeah, I did the music and sfx too
The intro drawings were made in 10-15 min each, the scenes were made also last day, most of the time went into the battle mechanic with the art of that part
