I've technically completed this game, but I have no real idea what to think about it.
The main gameplay loop is 'attempting to reach max love points each day'. However, this is made rather convoluted and difficult. You gain 'talk' points by talking with her, but this also increases her anger. If her anger maxes out, that's a bad ending. However, if you talk/interact with her, the guy beelines towards you at top speed, and gets faster the further in the game you are.
But you only gain love points if her talk is maxxed out, which means you not only have to max out her talk, you then have to flirt before the talk meter goes down, but anger also still rises, and the guy still runs at you really fast.
He only doesn't beeline towards you if he's currently occupied doing something, but he walks around so fucking slowly when he's not trying to hunt you down for flirting with his wife that if you try to play it safe you will always fail. Also, if he spots you flirting with his wife at all, his 'awareness' meter rises, and this reduces the amount of time he'll spend doing anything, so if you don't totally stealth ninja your way through this, you won't have enough time to actually flirt and get to max with her.
The download contains a cheated save, but the issue with that is that there are 'flirting' scenes, it's just that they require you to actually play the game, which means you have to dance around the incredibly tight and stressful song and dance of molesting her while trying to dodge the Flash.
Scenes are okay. It kind of feels like a mishmash of different assets mixed with 2D and 3D art, but I don't think any of it is AI... or at least, none of the sex scenes.
