This is one of the games that in my opinion suffers from the high ambitions of the dev.
Instead of sticking to a relatively simple story and a few important options, it dabbles into everything.
Attempts at innovative gameplay, a plethora of choices, which sadly make the game so overblown that it takes ages to update and a dev constantly questioning herself and her abilities and re-doing crap, because she's not satisfied.
Hence, we already have a remastered version with just four chapters in (and they are not at all big chapters).
The writing as it comes to dialogue and descriptions is fine in my opinion, when it comes to story development however it feels unfocused, unmotivated and well, simply not that good.
The game has some pretty standard characters, it also has one of the most annoying and aggravating female characters I've encountered in games.
I have nothing against slow-burn stories, in fact, if there is a lot of sexual content early in the game, there better be an explanation (like already existing relationships, a fantastic sexual god as MC, and a game not taking itself seriously for example) for it.
I also absolutely love story- and character driven games.
So why do I rank this game so low?
Slow-burn needs the right pace, there needs to be a pay-off and IMO you need to steadily up the ante with the LIs.
Go from kissing to a bit of groping, to heavy petting, to forms of sex without actual physical intercourse and then to finally "popping the cherry" or so to speak, which doesn't need to be a literal deflowering, but simply a way of saying the actual physical act needs to happen at some point.
So far, the game fails for me in this regard.
And as for characters, well they simply aren't that great and again, one of them is simply annoying and completely unlikeable, a hypocrite of the highest order and so insufferable, that you wish for some option to seriously hurt or kill her.
Unless you are a total blanket who gets off on being humiliated and treated like either a toy or an enemy, for no fucking reason, other than that Chris believes she is the lady and mistress of all she surveys.
Yeah, no matter whether you are aggressive and "evil" or friendly and open, this lady needs to lord it out over you. It has nothing to do with MC and her both being military, you are of equal rank and at least on the ground it's actually the MC who would be the leader as the more senior officer in that regard
I'm expanding a bit on my POV about the character in spoilers, because it's just my personal view of it, and it might not be that interesting for some, it also isn't the major factor for my rating of the game, but if you see the long rant about it, you might think so.
So, to sum it up, the art is really good at times, some of the writing is good, the overall pace and plot has its problems, the characters work fine for the most part, but aren't written particularly great or outstanding and one of them is a massive pain in the ass, with no option to put her in her place.
