[Dead as Disco] Arora (Intense Difficulty, Five stars)

Shout out to TheSeedlingArtist for making me aware of the fact that throwing a Drummerang at an asteroid, then using Rush Down will sometimes let you do a boss finisher for extra damage. Second, screw getting this boss fight. It's not necessarily hard, but it's annoying trying to get a good time bonus while dealing with the armored enemies on this level. Plus, Arora is an annoying boss to deal with in general. This took me way more attempts to get five stars on than any of the other bosses.
