Here are some of my ideas, and perhaps I'm the odd-man out as I don't see many posting ideas relating to this, so that might be an argument against my recommendations, but they are character development points which you've hinted at that I have become quite invested in.
The Robot: I kind of want to preface this by listing my experience with the game, as I avoided all bad endings and enjoyed very much simply building up my relationship with this robot. Shows how I'm probably in about as healthy a mind-state as Anon, however I found it quite satisfying. Watching her develop a sense of self made this story very interesting for me, and so by and large my ideas center around that. Additionally, I work from home, and this story line of this single shut in really resonated with me, so perhaps I've attached to this a bit too much as wish fulfillment, which is something I generally don't like out of anime as I don't think it's healthy. Therefore I tried to evaluate this game under that same mindset.
- Her acting differently based on what name you give her, and what you have her call you. For example, I didn't feel right having her call me Master because that's.... Just not something that appeals to me. I had her call me Friend. Perhaps she could act differently based on what kind of a relationship you try to establish with her. On the flip side this is kind of a hidden mechanic that might shut out people that are more appealed by being called master from that part of her dialogue, which maybe you wouldn't see as a preferable game design choice. I find this idea interesting to play around with, however.
- Having her become more animated during sex. She develops more of a sense of self and her own desires, I understand she's still a sex doll, but I would find it appealing if she acted out her sexual desires to the player, eventually, as their relationship grows.
- This is more based on game mechanics, but being able to spread her pussy during anal. Seems like you cant use your hands at all down there with your dick out. Or messaging her while having sex to maybe get her to the "ahegao" face more easily.
That's really it for my recommendations towards her... I like the idea of her developing more self agency. However, the game is not complete yet, and who knows what she might be like some day. She has already planned out the enslavement of all mankind. That being said, for those, and probably a good deal, of us, I find it very endearing to watch her relationship with Anon grow through a non-bad ending. Perhaps this wasn't the intention, but I have gotten quite a bit of enjoyment out of it.
Specifically why I enjoy her developing self agency, is because in my eyes that is what will separate this game from being wish fulfillment to being well written and interesting. If she ever disagrees with Anon, I'm interested to see how that story will go. I'm very much here for the story, and have enjoyed it greatly so far. These are just hopes for what you have planned in the future. I think her character is already leaning towards being well written. She sees no issue saying "use me please!" Because she's a sex bot. I'm sure from her perspective that's the same as a human saying "I want you." To us it is obviously foreign, that's part of what makes this interesting for me, is her different perspective as an AI.
Aside from that, I have some misgivings about the difficulty of the game... I get this is a sex game, and maybe this will be another outlying suggestion that no one else agrees with much, but I don't find it very difficult. For the most part, even in a fresh new game, you can very easily make rent and start getting robot parts in a few days. I won't specify how so as to not ruin the experience for other players, but perhaps a more complicated system to develop this, or some sort of a difficulty system for us crazy players such as giving Anon stats that you can raise, and making the base stats higher or lower depending on your difficulty in the game.
Here are some ideas for game difficulty:
- Giving Anon stats for different actions such as using his hands to pleasure her, having sex, stamina, the amount he can cum per climax, and the amount of times he can climax, based on any combination of his skills and his physical health.
- Making the Robot more or less satisfied for her own personal needs based on the skills of Anon. If he's poorly skilled, perhaps she is finding herself desiring his presence much sooner, and this could have a positive or negative affect respectively, if she's satisfied or unsatisfied.
- Changing these base stats based on the difficulty of the game, that way people that play for the story can... Still do so. Meanwhile us weirdos trying to get through a hard play through can have our cake and eat it too.
- Make his base skills increase through his activity, and decrease based on his physical health or his healthy/unhealthy habits as he runs out of energy. Or just decrease over time as he fails tot use them.
- Creating a formula that adjusts how many additional viewers Anon will get per minute on average, based on his skills.
- Or perhaps how turned on the Robot is. If Anon's skills are lacking, and he cannot get her to the "ahegao" face, perhaps views will suffer.
Higher stats might mean you get less views as your less sufficient at fucking, or lasting a long time before climaxing, or perhaps the amount of cum you have per climax is limited due to low stamina stats or poor physical health. These are just some ideas. As aforementioned, I can usually be buying hypercamo robot parts before the first iteration of rent in a new game is even due. This isn't a criticism, I think it's important for you to understand your market, which you seem to. I think this is a nice rough draft idea, as it will make the game more strategy and resource based, enhancing the gritty feeling this world has where Anon is just barely scraping by. Again, I feel like the outlier in this post, but I do hope you'll give my thoughts some consideration :)
I didn't endorse this game at first, but after seeing your work, playing through start to finish, and evaluating the story for myself after playing it, it's enjoyable, and I plan on supporting your game moving forward. It's been fun!
