Rate I would give: Legendary
From my video: "...Great fury of heaven combines decoration that is very atmospheric and pleasant to look at with decoration that is super chaotic, colorful and high energy. Also, the way everything rises up and goes back down around the edges of the screen is a nice touch which gives the level a very fluid feel. Unfortunately, the gameplay is way too hard for me so I can't really judge that. Also the song is a perfect fit and I like it a lot"
