I have a couple ideas for the more lewd parts of the game. First of all, it would be great if there was an masturbate option. You know, like a button you press to masturbate in little sprite animation like with the mating scenes. To add onto this, you could also put collectible sex toys throughout the game which you can equip in the Q menu. Example: a basic dildo, a *magic* vibrator, a big dildo that you can ride, ect... As for how this would work for gameplay, it could slowly lower your yellow bar if you want to get mated with without taking damage. It would also be cool if you could like automatically trigger sex scenes at the inn. To add onto this, you could have unlockable partners that you meet throughout the game that you get to fuck at the inn. And, when you don't have any, it could be a masturbation scene with one of the toys you found but in a more detailed animation. I know that one is a big ask because it would require more of the high res animations which is a LOT of work but it would be super cool! I think it would also be cool to have a brothel in town as a little miniquest/minigame. You could have sex and earn small amounts of gold for your efforts! I don't know how you feel about any of these but those are just some ideas that I have! This game is really fun and I wish you luck with your development! If you like any of these and would want any more help from me, let me know!
(P.S. I have not experienced the entire game so far so forgive me if anything I have listed is already in-game)
