I'm really excited to see where the story goes and hope this feedback helps!
1. The MC didn't come across as partiuclarly feminine, cis, or white- then again we're only one chapter in so that might change? As a brown skinned Latina it's super important to me with customizable games that they don't feel super white-washed. Will skin color/ethnicity change the way people address or speak about you in the regency era or is that avoided?
2. As for choices in making an MC, again I feel like it's a little soon for me to have a concrete opinion about it. I'm guessing throughout the story we will be given choices/dialogue/reactions that will solidfy our character in the world. I will say the options you gave us in demo were very natural and fitting within the chapter.
3. I didn't catch any spelling errors. As for awkward phrasing I think that's more to do with me having ADHD and getting into the groove of reading, especially if someone has a particular writing style.
4. I found nothing within the chapter offensive or ignorant.
I hope everything goes well for you and you can get past any roadblocks in your mind with your writing. I feel the same when i'm writing, the constant overthinking and asking myself if what I've written is good enough. Good luck! :)
