I can see why the game is popular. It's good a nice style and a game loops that actually works.
But at the same time; the UI animations and transitions make navigation way more tedious than it needs to be. You'd probably cut play time by 25% or more if that was all instant (or faster) and you got better options to navigate between scenes. The event triggers often are kinda sloppy; just go to a location, maybe something happens, maybe something doesn't. Go in and out to re-trigger something, saving only works at specific points. Characters are okay but there's rarely real development. You just achieve something, get a sex scene, maybe two, everything continues as is (there's exceptions). Sex scenes tend to be pictures with some inane porn dialog, there's rarely any deeper writing before or after. Balance is, well. There's absolutely useless stuff and then there's stuff that has extreme effects. Minigames are dull and usually just a bit too long.
I'd say okay game but could be much better.
