A part-by-part review from when I beat this.

Dudex: There is a certain expectation you have to fill when making the first part in a level, and Dudex accomplishes it perfectly. It's fun, expressive, and despite being early 2.1, the decoration wouldn't really look that out of place in a modern level. 10/10

Serponge: What are you even doing? 4/10

Manix: This part reeks of early 2.1, and plays accordingly as well. There are many inconsistent parts, but it's by no means horrible. 6/10

Rustam: You don't even need his name to immediately recognize his style, and his habit of putting detailed setpieces in his parts; here, the awesome skull, which is sadly very inconsistent to pass. The rest of the part is also very easy for an extreme demon. 6/10

nasgubb: For the part of the song that it's in, it serves as a perfect break and buildup into the second drop. Not much more to say here; his style is simple, yet effective. 10/10

ZenthicAlpha: The dual and the rest of the part can get decently consistent, but the movement is still very janky. For what it's worth, at least the spider spam isn't horrible to play. The decoration is also quite nice for early 2.1. 7/10

Viprin: 0/10

Pan: The dual is a massive chokepoint, the wave is inconsistent, and the cube is janky. Despite all of that, it's not completely atrocious, so it gets a positive score just for that. 5/10

Evasium: This part also reeks of early 2.1, even more so than Manix's part, but somehow, it's actually very fun to play, and the end, with the ship leading into the robot, which in turn leads to the wave, is a perfect leadup to the third (?) drop of the song. 9/10

Etzer: Just like his part in Digital Descent, it's clear that he really doesn't care anymore. It's shoddily made, and the gameplay is painfully easy. Why does the CPS get lower as the song gets more intense? 3/10

Terron: This part is just plain cool, which anyone can clearly see. This structuring, as far as I know, has not been tried after this, which is a real shame. A perfect finisher to the level. 10/10

The average score, then, rounds to a 6/10.
