Very true, it's more or less just a sex-sim. And a very easy one too: "Talk about work", "Talk about hobbies", "Become friend", "Confess" and you can H already. All in 2 minutes.I don't think they intended a sims-like to begin with. This game is all about to unlock H scene dedicated to specific room. You need to fil stats and build relationship to fil all the prerequisites, there is eventually 2 special scene per job. Enventually if you want sex between more character you can save the card thanks to the editor and use them in free H.
The game is all about to recycle animation and to dispatch them in a immersive situation, this is all about visual, mechanic are here to give some context. The game is very confusing because there is acutally no purpose and the game doesn't say if you achieve goal beside unlocking girl room. Maybe it is somewhat inspirated by House Party, haven't played it both more look more about sex scene build over some basic way.
That's why I loved AI-Shoujo so much (played hundreds of hours). That game had purpose, meaning, reason, progress, achievements and even an ending. And you had to progress with the girls in order to H or unlock positions, and they actually changed their character in the way you treated them. And when you got tired of H-ing or gathering/crafting items, you could build and decorate houses for hours in between. To me it's the only REAL game out there.
