One of the games on this site which absolutely deserves all its 5-star ratings.
The art is great, all the LIs are distinct and well-designed, and the game makes good use of the premise to show off lots of different settings. It also does a great job of showing LIs in a wide variety of poses, outfits, and situations, so there's plenty of attractive content outside the actual sex scenes. Usage of music and SFX is generally quite well done, too.
As far as scenes go, there's a good variety, and the first penetration scenes with the main LIs are all basically the peak of vanilla scenes.
Writing is overall quite strong. For the most part the characters are relatively believable, if sometimes a bit over-the-top, the story is engaging, and as it progresses there's plenty of character development as well. There's quite a bit of focus on various family struggles, which you can easily get emotionally invested in. Both suspense and comedy are well done. Dialogue is fluid, even relatively minor side characters have a distinct "voice." It's by no means a literary masterpiece, and it's not always completely polished; there may be a few scenes you'll want to skip through just to get to the next action sequence or plot development. One pet peeve is that the occasional use of *chuckle* or *shifting around* and that type of thing, intermixed with actual dialogue, can be a bit jarring and feels low-effort. The MC is somewhat OP and doesn't stand out much on his own, although relatively speaking it's within reason. Overall there's a lot to like about the writing and I would say most people wouldn't have much to complain about on the whole.
Despite the VR isekai premise, there aren't really "game" elements beyond typical choices in a VN, which looks like it was a good design decision based on the quality of the result. One thing to note is that the story is almost linear. In general, you are following one story where you are occasionally presented with choices, and you can simply pursue all the LIs simultaneously by making the right choices. You can forego any LI, and there are some seriously wrong choices, but there aren't major divergent routes or anything like that. In other words, you're almost never confronted with a choice between two equally valid options, which would lead to content completely exclusive to that choice. (The latest update has introduced the first such choice, but it's kind of self-contained relative to the main plot.) If you're looking for a game where you can mold the MC as good/evil or choose "corruption" paths, this is not it.
The technicalities are pretty well done, too - other than the generic save system - I really feel you need 20 or 30 pages of saves minimum if you want to easily go back to any major scene. It was nice, however, that the "texting" scenes were fully save-friendly, especially considering there's a lot of photos you can only see in that scene; there's no separate "phone" UI and these photos don't go in the gallery. The dev also makes fantastic use of animations throughout the game - whether it's showing off the girls, a sick action sequence, or simply adding that extra life to characters' body language - as well as little text effects.
