Hi, thank you for ya support.
For ya answer;
1) It a great idea but also a bad idea as well since you can manually press "s" key to screenshot the game and my schedules pretty tide to do extra artwork unless you can wait more than a years for the update. (Technically wont happen since im coincider the other reader as well, so I cant add those features)
2) They can see in the dark but the narrator will always noticed us about certain scene need to be noted or awared.
3) Spoiler wont be reveal unless you are Alpha Subscribers patreon.
I hope this answers your question and Im sorry if this answer might not satified the question.
