The upside down castle isn't amazing once the novelty wears off and you realize that even with all the movement abilities, it's fucking obnoxious to traverse the place while upside down, sure, but what other games do their levels one more time but upside down? I'm sure there's more, but to me it doesn't feel like it's common.

I've always assumed that the upside down castle was something they like, came up with or only got to realizing late in development, hence why it feels a bit halfbaked. Real cool to put it in there, but in hindsight there's some weaknesses.

Harmony Of Dissonance had two full castles, but it wasn't just the same castle again flipped turned upside down with some hue changes. Usually there were some noticeable chances of the palette and even tiles, as well as layout and features, which made them distinct, and you actually went back and forth between these two 'layers' of the castle to progress, as you couldn't always progress in the same spots, or you needed to do something in one castle to affect the other. It's much better implemented in that game.
Aria Of Sorrow doesn't even really do it, it just has a series of rooms redone for a short bit.

I feel sorry for you, but blame Sega for mismanaging the Saturn.
