So I have some questions and suggestions:
1: I think it could be neat if you animated the spirits’ sprites a bit during the non-mating interactions, like, say, during a regular conversation, a simple swaying idle animation, perhaps with twitching of the tail and ears, could certainly make the spirits feel more alive.
2: Tying into that, do you think cuddling and making out could have their own animated scenes? Having it be just a text interaction where the spirit smiles in the exact same way kind of breaks the intimacy / immersion.
3: The option to have the spirits display their genitals during interactions is nice, but it’s a bit awkward for, say, Sean to be at full mast over you buying a fruit off of him, or Ori to be likewise after confessing to accidentally killing the protagonist of Hollow Knight. Perhaps the spirit’s erections during interactions could be tied to their arousal, so, for example, if Ori becomes aroused during a makeout session or suggests to you that you mate with him, he would get an erection then, when it makes sense?
4: It might be interesting to have intersex / hermaphrodite spirits. You can already customize Ori to have some mix of both typical sexes, why not mix them further? A spirit with both options when it comes to breeding would certainly be able to carry on the species easier as well, so that could fit into the Spirit Tree’s ideals.
5: Does the earlier roadmap still apply? What stage would you say you’re on, if so? And what stage will come next, at about what time? I feel a lot of the upcoming features will do a lot to increase the overall feeling of comfort and deep intimacy.
