To tell you the truth Kuja, all the levels were good, and your explanation clears things up, here's a quick overview of what I thought of your levels.
Emerald Isle Zone: 10/10: Perfect, the catchiest theme song, for Act 1, that I've ever heard, and top notch level design, a bit confusing, but that's what happens when you have a ton of different paths.
Blaze Canyon Zone: 10/10: Some minor lag issues, in Act 2, but one of the longest levels, I've ever played, and Act 2's song is epic, really sets the mood, one of the best levels I've ever played.
Aquatic Labyrinth: 8/10: Act 1 is really good, but a bit on the easy side, Act 2, is a bit short, and easy as well, and lack of original music sucks.
Shale Village: 7/10: The level design is actually not that bad, but the theme's been overdone, and it's a bit on the short side, compared to earlier levels in the pack, but generally, a decent level.
Twilight Pass: 6/10: Easily the lamest level in the pack, it's a snow level, that's been an overly used theme, and it's too short, and easy, compared to all of it's predecessors, but it's still a good snow level.
(Desert Level): 9/10: I forgot the name of this one, but it's actually pretty good, the gimmicks are decent, and the return of original music, in Act 2, from Sandopolis Act 2, sets the mood, a really nice level.
I didn't play the special stages much, but you get the idea, it's a good pack, with noticeable weak spots, like I said before, but still one of my favorite mods, I aspire to.
