The fact she's "independent and free from many socially common taboos" leads to thinking your final outcome would be more than just one drawing of sex in cowgirl position.
2 minutes tops of gameplay to reach the 4 endings. And three of them don't give additional pictures, only a Game Over screen. The options leading to a game over are really obvious and it makes the "choice" aspect of the game really artificial.
Moreover, there's no story here. No unexpected events, no twist, no social or political comment, nothing that could last in your mind. You ask a girl for the direction, she invites you to a date, then she asks to go to your place, you fuck, the end.
The character design is decent. But the art for the sex scenes are a bit more awkward. And there's only: bikini picture ----> kiss ----> oral sex ---> cowgirl. Nothing out of the ordinary, and not even the bare minimum (the option to cum in her mouth leads to a game over, so you don't even see it).
Basically, this game's story would need to convey something interesting. The art should be present in much larger quantity. The choices should feel like a date sim. The endings should have additional art and writing, or not exist at all.
A short game better have an explosive impact on the player, like any professional short story you'd read in school. Otherwise, it's just a long story that ends too soon.
(there's no malice in my critique, that was my proposition on what the game lacks to earn 4 other stars)
