This game doesn't blow you out of the water with story, but it sets up the premise of porn game nicely. There are reasons beyond "big dick" why girls are inclined to throw themselves at mc, and it takes at least some effort to get to the 3rd base. You don't actually use some cheat-like powers, like hypnosis/lust magic/drugs , your succubus companion is more often than not just a dirty-minded wingmate that can sense thoughts/emotions and give hero hint and push here and there.
Can't tell where the main story will go for now, but potential for some twists, drama and adversities are there.
But the slice-of-life stuff is written nicely, all you need to not get bored: the humor, banter, side characters doing their own stuff and interacting without the mc involvement, having some backstory and possible problems to unravel when you dig deeper.
And since we talking about writing, sex scenes are also above a lot of other games - it's there, and it's not just a bunch of descriptions or some repeated moans, but legit dirty talk and emotional back-and-forth.
Cast is pretty varied - you have all body types and personalities, with faces being pretty realistic (more Daz, than Koikatsu anime look), but still having enough leeway to make good "paranormal" characters, like the bunny demon , or ghost girl. The paranormal characters also introduce some suspense and mystery to the story.
Now for the best part of this game:
The dev is wizard with HS2 engine, it's like reading full blown quality hentai manga . Never seen such masterful use of tongue and mouth rigs, you literally have scenes hot enough for boner where characters just makeout (or more like suck faces). I also appreciate extensive use of custom poses and creative use of animations - you can barely notice stock ones due to camera angles, clipping short bits out of full cycle, model adjustments, and especially specific posing renders for moments with no animation . All scenes look great, and there is no one scene that looks like another. Also love the custom cum work for massive cumshots, adds to the scene's passion and uniqueness. Amazing work, hats off to you!
And let's not forget about often overlooked sound design - yes, most of sex sounds you heard before if you played japanese h-games before, but they still add to the immersion in the background, while you focus on visuals and writing.
The music is also a breath of fresh air, it's not royalty-free stuff you heard 100 times before, but themed music for scenes/characters taken from (i'm guessing) some larger pool of japanese games. Nothing ground-breaking or distracting from the game itself, but it sets up ambience nicely.
As for the gameplay itself, I'm usually wary about sandbox types, but there is no grind here -you don't have to grind scenes over and over again, and getting stats or money is more like another scene progression set with one characters or another. I guess the only grindy part is the timeslots, as most of them are triggered in the same afternoon slot, and you might have nothing to do during morning-evening once you done with progression through "home" characters. I would like to be able to go out in the evening and trigger other routes, maybe some night-only creature as well?
TLDR this game deserves recognition as shining example of what HS2 engine can do in custom scenes and model department, and dev deserves support and recognition. I wish you success and smooth sailing with your future work!
