It's a shame that i can only give this a very mid rating, because i enjoyed previous game of this developer, Yotogimichi, quite a lot despite all it's flaws (at least this time girl doesn't look like shrunk titan). However somehow compared to projects from years back it's one step forward and two steps back.
Like his previous games, it's essentially a 3d simulator with physics and individual body parts being main focus, and it implements systems from Yotogimichi and Dereah like body positioning and others, so your goal is to quickly get through boring stuff and get to the main events.
This is where the issues begin. I was very much fine with one hour long prologue, since it's actually an improvement in storytelling and was a fine setup for the situation, but i can imagine an hour before getting into such a game can be an issue for people. Well, the thing is, it's just the beginning. Once you are done with prologue the REAL prologue begins where you slowly trudge through the days, increasing your level while unlocking other abilities like taking off accessories and clothes one item at a time. It was the same in Yotogimichi and it worked fine, but in here it takes UNHOLY amount of time to get through due to how game is structured. You have several time slots now instead of every location change progressing time, which slows the pace to a ridiculous degree.
Thus, the game loop: you take money out of the drawer, turn on washing machine, buy food from the TV, place food for the girl, wait until she eats (twice a day is generally enough), and the rest is you touching her inappropriately. The issue is, you have to repeat touching for every time slot instead of every day now, if you want to get this exp quicker to progress, which becomes a chore and like a speedrunner you start optimizing the gains with getting just enough experience to get to the next level.
To get to actual penetration, you repeat this shit for HOURS on end, and no im not exaggerating. While the prologue was fine, the prologue 2.0 takes absurd amount of time and kills your desire to do anything along the way by making everything a chore with a gameplay loop that fails to engage.
It doesn't help that, despite mechanical improvements such as actually having exp visible at all, you need to right click on her to see her alert and ecstasy meters (which is important since early on certain ecstasy will force her to stop), and it's only visible above her head, so you have to adjust it too. It sounds like a little thing but what it becomes is you touch her couple times, unlock your hands, look at her head, right click, check ecstasy/alert levels, wait until they go down, touch couple more times, repeat. It becomes less of an issue the further you go in but the beginning is a nightmare.
Which is made worse by general lack of polish, such as braindead AI (girl just stand and stare at the wall if you don't engage her), she can barely do pathing and walk into walls constantly, clothes freaking out and going through itself and bodies on a regular basis, and general emptiness of the world. Imagine, IMAGINE what it could be if she had a life cycle and you could do perverted ghost things when she, say, reads a book, is in a zoom call, invites a friend, having a bath and hundreds other situations, insane wasted potential.
And the main appeal, the whole controllable 3d sex thing, it just feels... worse? I can't really explain it with logic but it simply feels worse than it was in Yotogimichi.
I could be something really amazing but it just isn't. So many flaws, empty world, boring gameplay loop, VERY long progression until game actually begins, clunky feeling all around. I just can't in good faith say that it's worth playing it, but if you are a fan of previous works at least try it out and see for yourself how it is.
