I saw the work you posted on the cosmos and such to Twitter and YT, it's looking really good! As a dev myself I understand wanting to put out a good product (as seen by me never uploading anything ever :P) so I get why you've not posted an update in a while; you've been very good about giving updates all things considered. I didn't play around with the male options personally but the option to have masculine characters is really nice, especially in such a dynamic fashion (looking at you Ai Shoujo AI which has two different models for male/female characters). I always strive to have super modular systems in my games as well so that adding things is super easy and fun so I like seeing all the stuff you've been up to with the animation system and such.
Other than cruddy M&F games on Newgrounds, SDT was probably the first hgame I played as well; though I watched stuff people posted before I played it. That was before I found out I was gay but sadly there's no clit-licking version of SDT ;v;. The mechanics I've seen so far are reminiscent of SDT where you move your mouse and such instead of clicking buttons, it's a really nice feeling and that's probably what garnered so much adoption from fans, especially since there was a sort of resistance and such which made it feel a lot more real.
AI is a passion of mine and I understand that simple but real feeling desire. One of my favourites in that respect (and one that I probably bring it up too much) is Ai Shoujo AI which has a desire system where all desires go up based on their corresponding stat and when a desire reaches max the AI goes to do an action related to that desire (go talk to someone for social, sleep for sleep, eat for hunger, so on so forth), that system could easily include an activity desire where they go do what they're told when all other desires are taken care of or vis-versa and have the desires come second. I don't know exactly how the AC AI works, I only played one of the games but as far as I can tell each character has different activities they do during different times of day and there's a little gap where they move from one activity to another then just have it figure out where they should be based on the current system time. That's more a theory though since I'm more used to simulative AI ;-v-, stardew valley does something adjacent to that.
I totally agree in that UI should be more visceral than digestive (ala dead-space health bar or red vignette instead of a metre), it's always hard to do that though, you did a great job making it seem less software-y, the sex menu with the deform shader or whatever that was and the aura looking overlay to that looked really good and felt a lot better than just a metre or such. I understand the switch though and if you just crank up the intensity of the orgasm and in general visual and audio reactions, I imagine it will work really well.
It's nice to hear that the system is so modular; I've seen plenty of systems that are built for one sound for one thing (given those were a bit more amateurish than something this built). I don't expect you to have spectacular VA atm, this is more of a pre-alpha build than what I'd expect from the final game, it's good that--given the budget--you could populate the game with VAs. Amusing but logical that it's just you and your GF XD, low-budget squad! It's not bad VA btw, I don't notice much difference in EroVA stuff in the first place but it's very much suitable and fitting for the state of the game.
Orgasms in humans are interesting I find :P so much in the act and the reaction of it that can be played with, both from the giver and the taker. I'm interested to see what sorts of things you'll be implementing as time goes on.
By the way: is the game going to have any built-in modding support? It would be really cool to be able to add hairs, VA packs, whatever and whatnot if possible; I'm sure it'll get fan support anyways with time if it gets popular enough ala-any big modular hgame, still would be interesting to know if that's a plan or too far in the future to think about atm.
No problem! On another account as well I put massive novel of comments in the sections below games I really like or projects I'm interested in; I fear I usually come off as a blabber-mouth with this 800+ word comment... It was nice to get a reply! If it means anything, you're work is a bit of an inspiration for me to get off my rear and buckle down on a single project, seeing all the cool stuff you're doing is really neat! Anyways, that's for the reply and keep up the good work! Cheers!
