Alright so far, few things still need to be added and a bit buggy.
Around 30mins long (21 day time limit), Only found 2 scenes (one text only with a maid and another that has a few gifs with the tavern owner (has a few variations)), transformation is just transforming into other women in the castle trying to line up what the King likes, small chest or higher to leave. Few bugs like "Your Femeninity is $yourfeminity" and possibly a bug that the King likes some things that the gossip said he hated (I had the gossip say he hated flat chests, went big, King in his assessment said he hated big and liked flat chests).
One more thing is to talk to the girl at the tavern to level up your seduction. Found out late, unlocks both scenes.
