i dont think there is really much of any fullbody-centric content, top or bottom. otherwise not really sure what you're asking, do you mean npc on player character interaction? because there isnt much of that either as far as i know, a few poses where characters are humping i think, and whatever poses where you can posess the bottom. beyond that afaik its up to you to pose characters how you want them and self-insert (pun? double entendre? both? you decide lol) the playerbody feature is relatively new outside of VR and and i dont think its much of a focus for them even in VR, or at least thats how it feels. kind of makes sense given how little utility there is for FBT outside of social experiences like VRchat and stuff like avatars for beat saber
I tend to agree on the relative lack of any substantive gameplay changes, its largely been new animations, the occasional new character/skin or location, but afaik very little in terms of new or substantially improved gameplay mechanics. personally i'd like to see the characters be more interactive/emotive. right now they're not much more than a poseable and slightly interactive fuck toy with dialog lines, not terribly immersive. they dont have any idle animations, they dont really have any AI (in the gaming sense, not the chatGPT kind of sense) and pretty minimal reaction to the player character outside of some context sensitive dialog lines.
i've also previousl voiced my complaints about the physics system/animation/rigging though they have actually made some recent improvements in that department (ie autofellatio and neck/upper torso flexability) the lack of any kind of ragdoll physics or colision with the environment when posing (other than the tail freaking out whenver it touches something) is a little disapointing given we had that in garrys mod like 20 years ago lol. would be nice to at least have floor and furniture colision with some compliance/IK so the feet and other body parts dont clip through the floor/furniture when posing. full ragdoll could be fun too, with weight and gravity, would make them feel like an actual body physically existing in the space instead of just a posable model.
I also complained months ago about missing changes that actually improve the game. Instead it looks like they are fixing the same bugs hundreds of time for some reason (I know development is hard and I have seen how tricky it can be but I wonder why they don't check for the same known reappearing bugs before releasing.)Maybe it is also just because I don't have VR and 2D controls have almost no priority in improving.
But I can somehow get what the problem is when only one person works on the game code. They have their own specific goals and usually don't listen much to the feedback of their team, at least if the feedback tells them to add or fix specific "problems". Also they often try to delay code rewrites as long as possible because a planned feature would need to change basic code logic, which would throw everything above back.
They are currently maybe just sticking new things together with tape so it can holdr together somehow. But it will break apart if it needs more substantial changes and might cause the dev to completely rewrite the whole code if they didn't have much experience before to structure it properly and modular enough.
This is what I experienced, but I wasn't the dev, I was testing and map design in close contact with the team before I left because of that chaos. I think the whole game was rewritten two times and the mechanics many more.
My usual rant part:
That is maybe a mean thing to say, but I absolutely dislike Twitchys animations. They are terribly cringy with that "twister game hand moves" which the characters do everytime they cum - [O-face, left hand down to blue, right hand down to red, finishing O-face, right hand back up to green, left hand back up to yellow, first stage sex loop starts again]. He either newer saw real porn or already reached his skill max years ago...and that is not exceptionally high... Quantity over quality for sure.
I also did animations and I know how much effort has to be put into good movement, but not realizing something is not right and natural looking is either ignorance/carelessness or missing skill. I think he just doesn't care because sometimes his animations have been above avarage and even good. If he would just leave out the Twister-Play keyframes I wouldn't feel the urge to choke him with his own oversized bat dick for this dumb quirk in his animations.
