Little late on responding to this, but here's the now-traditional wall of feedback!
This level's visuals were... a bit disappointing, to be honest (besides the final area, which looks amazing). They weren't bad, but the visuals (along with the roomnames!) are one of the highlights of the alphabet levels for me, so the more minimal use of Direct mode was a bit underwhelming. Especially in the Warp Zone area...
This seems to be the hardest alphabet level so far, especially the trinkets and Warp Zone. Mostly this is fine, but I think 'Kollision' was probably a bit much. The whole level could've used an extra dose of checkpoints, really. 'Kactus' was also unusually difficult.
I like the 'glitching' section - it's a very visually-distinct area, which fits well with your strengths. It could've been better foreshadowed, though - your post made it sound like this was THE BIG THING in the level, and it only really came in at the end. Maybe a couple 'corrupted rooms' scattered throughout the early section would make it feel more natural?
Also, I've got to say this because this is like the seven billionth time I've seen this in a level: WHAT THE HELL IS WITH PEOPLE AND QUIZ SECTIONS. They aren't gameplay in any sense, they're completely asinine as puzzle design goes, they're REALLY easy to trial-and-error so knowing the answer is barely even important, the questions are always completely arbitrary (why do i need to know the chemical symbol for chlorine to play a video game, this isn't a science test), and their entire purpose, regardless of difficulty, is completely invalidated for anyone with an internet connection, which you need to play the level in the first place! A quiz is, like, the premium example of terrible design, and there isn't even any interesting design or roomnames in that section! KKKKKK would be objectively improved in basically every way without that section.
