A character-creation-menu with submenu instead of a list with all species in it.

Would become handy when more species are in the game. Like:

Canine -> Wolf, German Shepard, Arctic fox, Red Fox, Fennec, ....

Feline -> Lion, Tiger, Panther, Cheetah, .......

Equine -> Black Horse, Spotted horse, Unicorn, ......

Scalies -> Dragon, Raptor feathered, Raptor unfeathered, ....

etc.

Characters who are actually blind and have heightened (sensitive) senses. I feel like it might have interesting dialogue and interaction, and how they imagine things and color they haven't known before/their entire life.

I do not intend to offend anyone...

Having a bunch of people at once, all nearby. Maybe all standing straight up, or all laying next to one other, or something similar. Limits should be in place to not out-do the rest of the game's content in terms of what can be done to them (maybe automated things only) and who can be there (only squirrels or rabbits or something, for sanity of coding / rendering). But ... would be entertaining in its own right, and maybe a late-game source, high-yield source of samples, and only available once your lab has progressed and become popular in the squirrel community or something. Would be a natural reward of progression. Certainly would lack as much of a personal touch, but maybe that's its own fetish.

Painlessly removing or swapping body parts between subjects, especially genitalia. Sciencefully.

Possibly with a room to store/collect 'borrowed' parts.

e.g.

Press Ctrl + U to hide UI

I know that there was already a suggestion some 3-4 years ago where the idea was basically laughed at, but in recent years - as the title says, Valve is now far more open to 18+ content, including quite a few games with outright sex scenes: Knowing this, would it be at all possible to get a Steam release?

If enabled or a d*ck is big enough of a size the "client" should probably choke on it.

This may not be everyone's fancy, but I would like to see species such as snakes, crocodiles/alligators, maybe grasshopper, etc... just putting out ideas. If it's made right it could be good.

That would be cool.
