Howdy!
Generally speaking, I'll add any kinks so long as I feel that I can write them to a quality that players will enjoy. There's plenty of stuff in-game already that I'm not personally into, but that was requested by players and that I felt confident enough to pull off to a standard I'm happy with. Obviously, if I'm not super knowledgeable about a kink, I rely on players to fill me in, but everybody's been incredibly helpful whenever that's been the case so far.
In terms of the kinks you mentioned specifically:
- Foot/Paw stuff is planned and a few pals are already advising me on stuff to include.
- Pet-play is already featured in a few scenes throughout the game.
- A bunch of scenes and bad ends have implied peril or snuff, but I'm uncomfortable specifically writing scenes where characters die, because I don't think it fits the vibe of a porn game.
- Cannibalism/Cooking vore is not planned, because it bums me out. Sorry!
So yeah! I'll add kinks so long as they don't make me sad, they're thematically compatible with the game, and I feel confident enough to write them in a way that players enjoy. Rest assured that any extreme kinks will always be sorted by planet, non-mandatory when the main questline is implemented, and completely optional.
Thanks for the question!
