Not at all. Sometimes cliche is good. However when your gimmick is twincest, and then you make the plot twist NOT twincest, its flat out false advertising. Its like playing Castlevania, and then suddenly having the last level be something out of Contra. Yea… its surprising, but it makes you do a WTF reaction.
The game only has three winnable girls - two of whom are the twins… that’s seriously low count for the type of game this title is trying to be. Yea… you have eroge with only one girl in it - but they are framed within the guidelines for such things. This title was framed as twincest… and a 4chan’er might put it: the game is FAIL
