I haven't played, let alone beaten any of these levels, so I'll be writing based on visuals only

Scream Machine by TMCo: Really, really love the many many callbacks to horror media in this level. Rather nostalgic in that sense whenever I can recognise something as a reference. Even for the parts that I don't theyre almost always something rarely done in levels in general. Not really any standout parts in this one as theyre all very consistently great despite a good amount of deco repetition. Unfortunately as a result of this homogeny in quality and style it does feel like it drags on for a bit too long especially since the song does drag on too [8]
REDEEMER by hhxa23: Usually not a fan of hazy visuals but I think they're generally done well here. Not even the best part of this level though, that goes to how well the end is considering there is this enormous buildup across the entire level that only releases at the last 10% [10]

Visible Ray by krampux: Old megacollab that holds up quite well today. Obvious issues with cohesion and deco quality consistency but it's not as bad as it could be. The more colourful and dynamic parts are pretty good in general [6]
