as for chapter 4.
-69 new animations
-300+ new images
-possibility to name our mother's character.
-Option to kill or let live a certain character.
now the game has a total of 279 animations.... shit I can see why it now weighs 2 gigs XD
p.s. it is possible that the android version will mark you with the name lesbian paradise (I don't know why, but that's the way it is) but don't worry, when you enter it will be chapter 4.
