What Android model and version (OS) do you use?
That's great I really love this game. I love the way the programmer developed it to bypass the incest policy on Patreon. I love to figure out what code he used to customize the relationships. There's a disadvantage with the Android app version I use the windows version with game interpreter called JoiPlayer they also have a Patreon. I use that app because it's hard to backup the save files from the Android version. Make sure to follow the FAQ.
