Seconding the above. A strong narrative that can carry the weight of the story on its own doesn't strictly need screenshots or other ancillaries, though using a few for scene-setting or embellishment could certainly go a long way.
As for general story concerns, I want to put it on record that I've been enjoying this tale immensely
If there are any formal or structural issues with the writing, they are few and far between enough that I've never really picked up on them -- no glaringly obvious typos, misuse of vocabulary, etc. I couldn't speak as to plotting -- it's definitely a bit of a "slow burn," and the make-or-break point to those is always in the payoff (which of course we are yet to see), but the story as a whole has been entertaining and thought-provoking thus far.
