No idea if this kind of game actually exists (it probably exists in some form in this forum), but if you could make peanut gallery comments to the current part/characters of your comic/novel, what would you say? You can also do it by chapter or by overall story or even by character, or whatever!
Peanut gallery comments as in: Any unnecessary/unasked for advice, commentary or suggestions you'd give to poke fun at yourselves/how the plot/characters are going!
Just get that inner snark and have fun!
For example, I've got three stories and I wanna do this for all of them. I'm gonna put a random peanut gallery comment I have for each one:
Bro bro bro is it so hard to just beLIEVE the dragon
It has been literally only one chapter since the werewolf boyfriend has left, and I miss him already RIP
- This is nice and all, but we are 34 chapters into this "Romance" and you haven't even kissed the goddamn robot once,
