Giving it 5 stars due the quality release, replayability and potential.
The dev clearly is following a "genre" he used on his previous game, College Daze. There seems to have a little more effort in the plot, less focus on "random" special powers, and focusing on a theme which gave him success on his previous game.
As mentioned, the game is still on the earliest releases, but it is noticeable the effort from the dev to polish a formula he already had sucess. And since it's an whole new project, then probably the organization in coding will help him to develop the story faster than it's predecessor. It isn't a masterpiece yet, but I'm sure it will.
College Daze already was a masterpiece, and with the polish will probably reinforce that. My only con is that I would like a bit customization on some characters (like for example, allowing the brother's wife to actually be your sister and the brother being the husband). After, I like a "good guy" route with the family members, and on this game and previous, both relationships with the sisters started on the wrong foot. And protecting your sister as a victim would be cool, instead of every sibling being a dick. The fact you can only slave the (actual) sister feels meh to me. This is just an example, but I would like a bit more customization in that part. I have no idea if that's possible according to the story of this game, but at least some characters of College Daze did, I even focused as only family members having power for example when modding myself by fun. Nothing gamebreaking but yeah, customization is always cool
Anyway as I hinted above, the replayability will be a major pro in this game. Sure it doesn't have much yet due early releases, but I'm sure it will have in the future, and besides the sexy stuff, the replayability is what makes a game good and memorable for me.
Easy 5 stars from me, not only due quality release, but also due dev's history, fan engagement and quality product. Depends only from the dev to continue the quality. Definitely worth of supporting.
