One, I read this on my phone so no good speech specifically and invisitext in a more general sense are not fine.
Namely they were not fine for much the same reason that the Queen of Fables flopped for me, they detract from the story's readability.
In a quite literally sense for both of them. I have to go out of my way to get those extra bits of story I any scene with a new god, and during the whole play thing it took me a while to even realize what was happening because I tend to skip non story posts unless something happens to randomly catch my attention.
In writing a story, your main goal and purpose is to convey ideas to your readers. Anything you deliberately do to make it harder for your readers to understand what you are trying to convey is counterproductive at best , and as I said is usually just down to pretentiousness.
What Zoat is doing with these gimmicks is [no better than those people on fanfiction.net who sprinkle random Japanese throughout their anime stories.
The only difference is that Zoat is telling a story I feel is good enough to struggle through his moods to actually enjoy.
