I'd argue that this is one of the, if not the best, H-Game currently available here. It has been around for some time and had the funding and time to amass a sizeable amount of content.
The art style might be a problem for some, but I don't count myself among them, I think it's good and has improved over time. There seems to be a certain preposition to make similar designs for characters (seeing how most of the women have extremely big breasts) but there is still plenty variety to be found.
As for most H-Games, characters are pretty stereotypical and basically every character behaves exactly like you'd think they do if you only looked at their artwork.
As many other people do, I think the minigames are extremely unnecessary, they often aren't fun to play, they seem to be rather complicated to implement and don't really offer anything. There are certain games I find okay, like the rap minigame or spinning the bottle. At other times, they are just frustrating (like fishing) and don't really offer any value, as I'd argue most people don't come here to play some poorly implemented version of guitar hero or need a minigame that comes down to you pressing A and D alternatingly. It's a VN at heart and should probably stay that way, especially since it doesn't utilize the forms of interactivity that it could use best, like puzzles.
In contrast to most other people, I think the story added makes the game worth to play in the first place. I don't think having story just to string together H-scenes is especially good, because those are generally very samey, it's the surroundins that put them into context and allevate them. I think that is best seen with the Roxxy route, I think it was pretty good and delivered a decent explaination for why they'd end up together.
Speaking of that route, I think it symbolizes a problem the game itself has when it comes to which H-Scenes you do and don't get. It fails to utilize characteristics of most characters when it comes to H-Scenes and instead aims for delivering the same scenes in many forms. Roxxy for example is shown to be teasing the MC with her boobs the entire time, pressing her arms together to make them appear as big and pushed up as possible but they aren't really utilized in her scenes, there is a lot of teasing involved, like having them be the main focus in the masturbation scene or having them be involved in the changing cabinet scene at the beach, but they are never involved in sex. Same goes for the mouth. She is very orally fixated and is constantly playing with a lollipop, but that isn't reflected in her H-Scenes at all. Missing these opportunities to create the same vanilla sex scenes for basically all characters is one of the weaknesses of the game. With the time it takes to draw each scene, the time it takes to produce each update and the time invested into things that aren't really core the gameplay, there could easily be twice the H-content per character, properly paced throughout their entire story.
Another strong point of this game is it's lack of repetetiveness. Yes, there are stats to grind, but it's not so much "grinding" as it's a mild annoyance. Other than that, you won't farm affection, attraction or any other kind of meter that has to be filled by doing the same thing over and over. For the most part, every interaction will be important and you won't have to do unimportant ones at all.
That being said, it can't be ignored that the game (as of now) requires you to play through it again for every update, making the otherwise promising aspect of intertwined storylines a chore. Having to play through several routes before being able to access new content is asking a lot, especially since the game is only growing.
For a first playthrough, however, you will be treated with a broad variety of options, many scenes, many characters, a lot of playtime and opportunities to expand everywhere.
Every update brings new characters and possibilities that are opened up, making you ask yourself wether or not this game will ever be finished.
In conclusion:
Pretty great game, somewhat short of what could be if the ressources would be focused better, but the best we have at the moment.
