1. it'd be a bit of work, but giving the bot different dialogue types would be nice. like you can make them bratty, more submissive, or even really excited, etc. so that during sex scenes they can giggle and blush, or give a little frown and tease you. maybe only during sex scenes, so it's less coding, and more situational, since you've done all the dialogue already.
2. maybe give the option to have the sections where the arms and legs connect be seamless without the lines of each piece to look more human. it'd take away from the whole "bot" thing, but at least you'd have the option to switch it on.
3. idk if it exists, but maybe after you connect with the bot enough, and have enough sexual encounters or enough ml of fluid in her, there's a chance of waking up to her on top of you, or a sex scene starting where she can't contain herself. maybe even an ending where if you deny her advances like, 10 times she gets fed up and yells at you or something and leaves.
4. a gallery where you don't spend money, but use ml of cum you've put inside the bot as currency to buy "sandbox" versions of the scene. like, put 250 ml in her mouth to unlock an endless mode where you can freely finish as many times as you want, and choose her level of "love" so it's like when you first start or when you gain enough love from her to max. maybe have pictures drawn by fans from patreon for 20 ml each?
5. this is just because it's funny, but have positions where you need something like 4 arms so she can go octopus mode on you lol
