Thank you for taking the time to write such a detailed and honest criticism of Bahadur's Story.
Most things, I can see your point -- but I do stand by the story. The main character is young, and she's written to be young. She and Bahadur do have an unhealthy dependency on each other (like you mentioned, she is his "purity token", his opinions are coloured by being conditioned to feel "shameful" and "unclean") but they are supposed to be flawed, pitiful characters who, by the game's end, have at least a hope of growing together and making a better future for themselves.
Of course, if that's not the feeling you got at all, then that's my failure as a writer, and I will seek to improve -- not just in future routes and games, but by looking back at Bahadur's Story and seeing if/where I can strengthen the backbone of the narrative.
It's probably one of the hardest things I've ever read -- to have Bahadur be called "Uncle Tom". I am genuinely mortified that this is a take someone could have, and obviously the absolute last comparison I'd intend to be drawn to this character. Though I would argue that breaking free of his servility (once admitting that it is in fact his own defense mechanism against the parts of himself that scare him) is a core part of Bahadur's story and character development -- not a reinforcement of the "servile minority" stereotype. But, regardless, this teaches me to cast an even more critical eye over my own characters, to ensure that they do not come off as unintentionally offensive.
Ultimately, I can completely understand why this game does not work for you, though I stand by it. I will certainly take some of the points you've made and aim to improve in areas I feel are lacking or misaimed, but ultimately Wilder is what it is.
Thank you for your feedback. It has been very valuable.
