Feels like dev has lost interest in the story or just doesn't really know where to take it at the moment and is just making sure to give some kind of update each month as a regular reminder that this game is still a thing until they figure it out. All I know for sure is that they're burning through their mechanics-update filler at the starting gate. Once the story starts moving again--if it does--there won't be much to go back and tweak, unless we should expect to start seeing a bunch of new clothing and hair/fur colors again. Ngl though, those sex mechanic updates are looking pretty good, which is why my dumb ass still bothers coming back to see if there's more story yet to allow me to use it.
According to the dev's blog, the current plan is to push out an Enforcer encounter for 3.8, then various bugfixes for 3.9 (thank god for that, the unfixed "minor" bugs are really starting to pile up), and then story content for 4.0.
It should be pointed out that both Helena and the Enforcer encounter were poll winners on their patreon/subscribestar, which explains why they get dev time over new main quest updates.
For me personally, I also love the updates to the underlying mechanics. The sex system is pretty unique, I can't think of another game that has such an interesting, deep and complex sex system. Just take the focus of this update as an example: Orifice streching.
Previous to this, orifices were stretched mainly according to the length of the invading object, with minor modifiers for the object's girth. Which resulted in dumb things like a 1 meter thin dick stretching a pussy wider open than a 20 cm fat dick. It made no sense. With the new system, dicks actually have a measured diameter, instead of being thin/average/thick, and pussies have depth values. That means that you can't fully penetrate a 1.2 meter tall imp with your 1 meter dick, and will get less arousal in sex. It also means that thicker dicks or tails stretch pussy wider than thinner, but longer dicks. And you even get an extra stretch effect if you force your knot into them when you orgasm. There's also now a "comfortable" and "uncomfortable" penetration depth, with comfortable being half as deep as the maxt depth. So your dick might be too long to comfortably penetrate a pussy, and you can decide whether to go deeper or not, with resulting arousal loss for your partner (unless they have the size queen fetish). I really love this whole overhaul, it makes the whole system work much better.
Now, if you're mostly in for the story, and don't care too much about how the sex scenes unfold exactly, I can understand why you would be frustrated. And the dev regularly misses their self-set deadlines. Like every single one, I can't remember an update being released at the date we were promised it. And as others have pointed out, the Axel quest still having so many placeholders is dumb.
Still, I'm a big fan of these mechanics overhauls. There are other areas that could benefit from some dev love. Like the fetish system for example, which is still in a rough state. So I hope they continue working on those issues. Not exclusively, and maybe their focus was a bit too much on those in the last few weeks. I'm also really curious how the story develops, beating the Lilin running around with the taurs in the Foloi Fields sounds like fun. So fingers crossed that finishing the Helena content doesn't take too long, and that we'll get 4.0 in less than half a year.
