This one doesn't really do anything special for me. The level is well-produced, but there doesn't really seem to be any sort of apparent theme. It's just a level that exists because Zoroa wanted to make it. Presumably because he liked the song. And while that's a fine enough reason to make a level, I personally am not a huge fan of the song, so it doesn't work for me.

This used to be my favorite easy demon a few years ago. Still holds a special place in my heart. The drop wave is just... Oh my god I love it.
