i'm going to have to respectfully disagree with your premise that this article is entirely "flow broken" because of the randomly capitalized letters and words. to me, that was one of the main factors which made me enjoy the article so much. it helped characterize the level in a unique way which i don't think could be done if it wasn't done the same way.
the biggest part of prose is making the prose be unique in some interesting way. if i were to read a book about crows, when i read another, i won't just wanting to be read the same crow story. sure, it can still be about crows, but i want something which makes it stand out in a beautiful manner. for example, one crow story could be about dead lovers, while the other can be about the thematic connections of the color black.
when reading this article, you have to understand that it is made up of mostly sensory feelings. the connection to the changing letters, to me, represented just how disattached those sensory feelings were getting. it was unique and made me personally follow along better, over if like, they just mixed some words up or something. it genuinely fit well for the buildup and the main punchline and dismissing it as a "loss of flow" is similar to making the argument that "all prose must be linear and straightforward and follows the rules of english," an argument which i personally find invalid and boring.
i urge you to read closer and reconsider your vote, as there is genuinely a lot going on here in such a short amount of words.
regarding the whole second part of your comment, please don't make unnecessary callout comments like such. it can be considered rude and shouldn't have an impact on your vote as a reader.
