The only reason I can't give this a perfect score despite wanting to is because of the inverted castle. The joy of exploring and backtracking throughout the first 2/3 or so felt almost undone with having to do it all over again but... this time upside down.

It doesn't help that this section of the game outside of the unique bosses just feels recycled, and not at all carefully crafted. A lot of the areas feel like a Mario Maker level or rom hack with multiple enemies littered and thrown around as if the developers were just having fun and letting loose at the end of the development cycle.
