I'm so glad you enjoyed the first game and this current demo! To answer your questions-
1. I'm afraid we can't have the MC be officially diagnosed with anything because there's a lot of neurodivergency and we can't write enough alterations to properly represent all of them. Being neurodivergent isn't part of a person we can simply state is true and then not show it in how they think and behave. So, players have to headcanon it instead.
2. Yes, there will be more curly hairstyles coming!
