This so far is my favorite game in this genre, even though it has some flaws.
Graphics: As usual these are of differing quality but generally good. The girls are interesting in their own right, even though some of the models are vastly overdone (landlady and her sister), the backgrounds are serviceable. The animation sometimes suffers a bit from too many parts not moving but gets the point across.
Story: It makes no excuses as to why you are free to roam around, just gotta roll with it. The paths sometimes intertwine but mostly you can concentrate on the girl you like. The pace of progress is almost perfect for me, even if it sometimes feels grindy (looking at you Sophia and our three weeks in a row daily sauna sessions) you are making progress at a steady pace without everybody jumping your bones instantly. This way the first kiss and/or touch feel like progress you will have to mull over. The "I" content is believable in the characters' hesitation and the ongoing "keeping it secret" part, apart from the BFFs of your roommates which may be a bit lenient here when they find out. Most of the writing feels organic and different ladies have different styles, but admittedly it's not reading like real literature.
Also unlike other games, this one doesn't really have an "ending" for each character which finishes the game. Instead you can "Think about the future with X", giving you a nice detailed ending, but then your thoughts are over and you can continue playing the game.
Gameplay: Unlike many other games with time, you don't have a "morning, noon, afternoon, evening, night" style of five actions per day, but each action and each movement between buildings takes a certain amount of minutes. Action possibilities only change at the full hour, but the UI allows you to one click your way to the next one.
Generally the UI is pretty good at helping you deal with some of the more pesky details like moving around in a house which often is complicated due to the directional changes from one room to the next.
The open time schedule also allows you to roam around at night and sleep during the day as you maybe would in real life, as long as you manage your basic needs for hygiene, food, and so on. The latter part can become a bit tedious, especially in the endgame, when you're only waiting for one action per day, but it can be turned off without repercussions.
Stat grinding in itself is minimal, you need money, sure, but the needs in attributes are filled quickly. There is a bit of repetition when upping the love meter of the girls, but it usually changes quickly enough to another thing to do.
Overall there also is a lot of content, and while some of the girls you meet are not dateable it also helps keeping stuff under control.
In the end it hits all kind of sweet spots for me, even though I don't even like three of the dateable characters that much (and have to follow one of them pretty far to unlock another one), especially with the very rewarding slow-but-steady progression you are making. I already played it multiple times for that and probably will again.
