Its a little interactive game with nice art, interactive as in, you press buttons.
Its short like others have claimed and its not much of a game in that way, though the highlight of this game and this devs other games are the Facial expressions. Given such, this game is worse than the last one since you're only on the ass side and can't interact with her face, so while your character is messing wither her rear end and your concentrating on that, you pay less attention to the details of her face.
Contrast this to the other game that only has blowjobs where all the action is on her face and expressions, you see her eyes lose hope and all that... This devs game are pretty dark now that I think about it, but the guilt is lessened since you don't have any story whatsoever.
