Good writing and characterization, gorgeous art. Can't trust them with numbers though. At all.
Did a quick skim through the walkthrough. Even the most hardcore, incest obsessed lesbian, jumping at any pussy tongue-first, double-fisting chicks left and right, would fail ALL Filthy score checks (even the basic filthy vs good wife checks could be close unless you compromise)
Dylan, Sam and the creepy mover guys are basically shoved down your throat if you want to avoid Good Wife points or simply rack up enough Filthy points for the scenes that require them. Going just after Ellie? Forget it, you'll miss out on all events/Ellie points that have Filthy score checks.
Good thing you can just ignore all this dumb BS.
Enable console (easiest way is via UnRen), shift + O, filthy += (amount)
There, now you can play out the story the way you enjoy it, see the content you want to see and, maybe even more importantly, avoid the content you DON'T want to see. Kitties >>> roosters.
