There are indeed many problems with Android, given the actual closedness of this system (those who say that the system is open have apparently never seen Linux).
In fact, the game now works fine with Android versions 5 to 8 inclusive.
Regarding Android: on version 14 the game is completely inoperable. Therefore, there is no point in using saves there.
Regarding character development, the survey results show the author of the game as the main priority among the players.
But this does not mean that the next update will be dedicated only to these characters.
In any case, in version 0.68 VIolet will get her episode.
