from changes log version 0.7:
Starting from version 0.7 of the game, I decided to make New! futanari content available only to those who support my game development.
In the public version of the game, there will only be sex content with girls who have pussies..
It would be best to add option to enable or disbale futanari content this why everyone could play this game and even turn MC into fullflagged female some why by labtest o him self. But locking just for making avaible for patron only ain't too much and unfair? I bet yes unfair. Just reales it for all and add an option in seting do disble or enable that kind of content.
