Steamdeck issues I can't really offer much help on - the main reason I'm not doing Android versions are because I don't have the time for development & testing on mobile platforms (also lack of hardware). I'll look into the seduction bug though.
Re: Character creator, glad you're enjoying it, but it's safe to say there's no plans to expand it at the moment. There are currently 13,563 possible player portraits not including clothing, which feels Sufficient for a game bringing in a couple hundred a month. Between portraits, CGs, etc, the game is actually currently spending several times what it makes on artwork commissions.
