Well you have set your own bar very high with this game, by adding one interactive hardcore porn scene early on, which features hot and juicy (and from the story context, consensual) BDSM sex. So the game more or less jumps instantly into the action, with several taboos covered - age difference, domination, anal, (etc.?).
This scene alone is, and promises the rest of the game to be, much better than all the hundreds of uncanny DAZ copy&paste games with their monthly updates. Usually featuring lots of hand/blow/buttjobs and mostly other forms of non-sex, of course on top of the endlessly bloated bla-bla-bla dialogues that nobody gives a shit about.
Also the overall game design promises something huge in the making, like an "open world" adventure game with a million things to discover at the player's own pace. Fantastic art, UI, even a visual advisor to help the player when he gets stuck, without having to play by a walkthrough from A to Z.
That the development seems almost painfully slow? Probably a sign that the developers are doing this by conviction to design a proper game, unlike the typical Patreon scammers who push update after update with progressively less content, until they jump ship after they run out of ideas to infinitely stall the progress.
And so far I'm just repeating my earlier posts in this thread; however after skimming through the posts my expectations may have been partly unjustified.
Romantic love as a topic in adult games just doesn't work, because players expect porn and things like seduction, corruption, taboos, or fetishes, and don't take "love" as an idea serious. And it is evident that you can't fall in love with a fictional character, at least not if you are outside of the target audience of steamy romance novels written for 12 year old girls.
And I don't think swimsuits were regarded as a sexually exciting topic since, let's say the 1950's? Sure they can be a nice starter for an erotic story, but for christ's sake - the past 3 or so updates have only been around the swimsuits, and the mechanics are already impossible to discover without a walkthrough.
Lastly, what is being promised as the only new sexual content after about one year of waiting? Ah yeah, a blowjob.
One of the same blowjobs that all the other average adult games are boring us to death with.
And don't get me wrong, a blowjob can be great and intimate, but it simply is not sex. Women have sexual desires just like us men, and if you're doing either the seduction or corruption right, any woman will eventually beg you to fuck her. While a simple blowjob is an entirely one-sided pleasure, which isn't even remotely satisfying for the recipient compared to real sex either *.
To sum it up: This whole "I'm doing you a favor..." or "You're so hot, so I'm gonna give you a BLOWJOB and then just WALK AWAY" is stupid, infantile and entirely depleted as teaser for future content.
Why not do it proper and realistic, for example by letting the MC literally get into the girl's panties first, give THEM a couple of orgasms until they're addicted and ready to spread their legs (and cheeks) at our command?
*) The only circumstances where an exclusive blowjob would be acceptable, would be something like - you are super-horny, but your wife/GF has an office meeting tonight so she won't even consider a quickie (because you're such a stud that she couldn't walk straight for the next 5 hours after that). But because she loves you soooo much, she gives you a blowjob so you shut the fuck up and leave her alone.

Well just my 5 cents, won't change the fact that IW is still in a decreasing list of adult games that I'm still going to download and play with every update.
Best wishes for the future development.
