Ok, so a lot of people complain about the infrequent updates to this game, and yeah, it's a bad offender of it, although the last two updates have added solid chunks, so it's not like nothing's happening, it's just sporadic, those who are paying for it may be miffed, but I'm a freeloader, so eh.
Onto the game itself, art's good, artist certainly has a certain preference for body types and some variety would be nice, but what're you gonna do. Animations are also nice albeit somewhat choppy but a game with dozens of 2D animated CGs give this game a niche if nothing else
Writing is passable, better than most games, but honestly that's not saying a great deal, it's simple and it knows what it's doing but it certainly works, what story there was in the previous builds is slowly being placed back in it, but to be honest I couldn't care less about it. There are character subplots and all, albeit very small, and while they do add to the game, the best parts of the writing is more just the quality you'd find in one off lines or paragraphs than any overarching content.
Summary : Great art, solid amount of content (that has slowly been put in), and decent writing.
