Exactly, the Big Brother to me it had great potential until 0.0.2 version, after that it became a complete disaster.Anyway, that game seemed to me too similar to "Big Brother", a bad game, IMO. I don't like to play as an asshole teenager always lying, peeking and manipulating his female relatives, and I don't like the female relatives being sexual freaks after the second update. I like a bit more of plausability, even in a game about incest
There are better ways to make the girls like the main character, and like you said i don't get why the main character always has to become stupid, or in case of Max from Big Brother that speak most of the game like he had 12 years old, among other things that make him unbearable.
I also hope that this Developer don't screw this game up.
