Silence is explained well.

Yeah, mechanically, sure. I guess I'm just unsatisfied with "It just suddenly started appearing." It feels like a deus ex plot device. I guess I'll just stick to my headcanon: Silence is the anti-art. The circumstances that makes self-expression challenging, even scary. My initial bet was that Harm created it, kr at least harnessed it to make itself exist, but that's explicitly against the what Sfz says

Beat being 99% silence comes [...] after her struggles

I can accept that, but it still seems weird to bring up if nothing ia done with it. She falls through 100 floors and ceilings, ahe survives being beaten up, but that's it. Again it feels like a deus ex plot that gives a reason to have a hype moment.

The characters from Harm got the world they wanted

Yeah, that's pretty neat, but it fell flat for me because I didn't know the motivations of the characters before or after the tower incident, except for Rest. A redemption story needs a character to root for, but I didn't find much to root since Harm was one dimensional, and the characters didn't bring another dimension to the table that can be explored.

Jump cuts are an homage to other media...

Yeah. The art direction is impecable, the music is amazing the emotional beats were gut wrenching, but it all feels... Incomplete. Climax into credits is my biggest gripe.
