Honestly... I wasn't expecting such a good game.
It has its flaws (I loved the background errors), but I loved everything I saw. Mia's dynamic with the MC, the interesting characters presented, the care taken with the models and scenes, the attention to detail—I find it hard to believe this is a first project. I'm deeply invested in the story and can't wait to see more. And I'm grateful for the road map.
My only "tip" would be to be careful with grammar. Not for me, but I know plenty of people who are capable of marking a game as bad if it has too many errors.
Again, a great game. Keep cooking and don't rush perfection.
