It's really necessesary that this game has a content warning so the audience knows what kind of stuff they'll get exposed to, rather than writing a walkthrough guide just for the people willing to play it. Scenes like scat, acts of beastiality, and an amputee fetish are some of the things that were never mentioned unless you're already far in the game, which can be a horrifying experience for some folks that come unprepared.
Unfortunate that the dev probably abandoned this game and won't likely address the issue judging by the lack of their response for almost 3 years now. So consider whether to play this or not, as it is also unfinished.
