Haven't finished it yet but I liked it quite a bit. It's a very "harmless" harem AVN in an isekai-fantasy setting that isn't really meant to have a deep and philosophical story. It's just nice entertainment, overall quite wholesome (despite it having some dark themes in the worldbuilding) and just good. Seems like the dev knows what the game wants to be and who this game is for, and is going all in on it.
Great.
The only thing that is a point of annoyance for me is that in some scenes, the camera itself moves along with the characters' movements and makes it quite jarring (for example, it's very apparent in the second encounter with the succubus girl, in the city while she's disguised as a human).

EDIT: I take that comment over the shaky camera during sex scenes back. It's fucking atrocious and ruined an enormous amount of scenes for me (btw a positive of the game - it has TRUCKLOADS of scenes, which is awesome. Great models, good quality animations... with ABSO*FUCKIN*LUTELY ATROCIOUS SHAKY CONVULSING CAMERA). I have no idea why the dev chose to set the scenes in that manner. I'd honestly advise he go back and redo every scene. *EVERY. SINGLE. ONE*.
"Oh but it's a lot of work and no one's got time for that!" --- then it should've been done right the first time around. Just fix it now and keep it fixed moving forward please. It's bad. It's really fucking bad, and it's a shame that it's as bad as it is.

Other than that, I don't really have harsh criticism for it. The models are pretty great and the animations are pretty good too.
It has decent internal logic and consistency, at least from what I've seen so far. Some of the jokes didn't land for me, but I still appreciate the effort and the goofiness (in some aspects, gives me some konosuba vibes), and some of the devs references to pop culture were also nice.
I'll be looking forward to more of this, and will be recommending it to folks, with a clear warning regarding the convulsing camera during scenes.
