Although the writing is decent and, at times, above average, the extremely grindy and punishing nature of the game make it a chore to play. Hidden one time events, the day advancing after a single action, the need for money that can only be earned through sheer repetition, the absence of clues, the lack of interesting mechanics, the random nature of some events all contribute to that.
As is the case with many of these games, it does not have an overreaching plot, which make the grind even harder to stomach.
Although I appreciate the effort in trying to animate the sex scenes, in my view they are not worth it. Even when the animations turn out to be decent (as opposed to robot-like), the time spent on them could have been used to add multiple renders and make the sex scenes more natural and less anti-climatic. As it currently stands, several scenes start and end abruptly with some exceptions (e.g. college visit). The dialogue during them is also lacking since it's composed of just a few lines (sort of expected considering its focus on animations as opposed to single image renders).
Another problem is the constant addition of new characters while the old ones are barely developed. The game, even after all this time, still feels very bare bones.
Another flaw is that there aren't nearly as many locations as other popular "free roam" games. It wouldn't be as problematic if the game allowed more interesting interactions with each character in its current locations, but that is not the case. Instead, the lack of non-trivial interactions and dialogue with other characters exacerbate the grindy nature of the game.
Furthermore, until recently, the game suffered from the "magic pill" problem (like Dreams of Desire but to a lower degree), where an item was used as a replacement for relationship build-up and interesting dialogue. Even now, after the removal of them, the game hasn't been able to fill those now unexplained gaps.
Finally, the developer has proven to be quite unreliable and the game has been virtually frozen for months. It is true that the Patreon debacle is in part to blame for that, but many other games overcame it.
