I think pronoun selection would be great! I feel like it creates more immersion if that makes sense lol. Music didn't disturb me or anything, I think it helps creates atmosphere as much as the beautiful art does. Speaking of which, the colors, universe, and art style or Magenta are literally everything. Creative, compelling, and just AAA omg I can't wait for more. It inspired me to start creating again so thanks lol.
The number of choices in the demo was good! Not too much, not too little. Sticking to 2-4 choices would make sense, I feel like that would keep it simple and not overwhelming the player with choice. Though I know I will be saving at the choice options so I can see every possible interaction lol. I think it would be pretty fun if the festival had a background character that was all vampire-victorian styled, that would so eat in your style. Wishing you the best!! :)
