Hmm. Despite my cartoony style, my story does contain a bit of blood, and swearing is mostly censored, or nothing over 'dammit'. Might be PG atm. But that's probably gonna change real soon, given the gradually increasing intensity/drama/themes, and one of my characters would be in dire need of releasing an F bomb, but that's further down the road.
There are a few lines I will not cross (no onscreen sex, but plenty of sexual refs/humor, cause its cocks/roosters. Gore/viscera? unsure still, but it does factor into the story (deals with a slaughterhouse). Might find creative ways to censor those moments.)
I'd give it a 3 or 4, for how tame it is rn, but I'm thinking it might go up to a 5-6 (PG-13, I'm assuming) in the later seasons (let the kids grow up reading it and be slowly traumatized, hehe).
