Hello! First of all, I love your name. Secondly, thank you for these questions.
A) No, because it's my first game and I don't have the technical capacity to do it yet. Character customization requires some bug testing and a lot of art resources so I won't be implementing that for this game.
B) Yes, but in a minor way. I will try to maximize every decision the player makes so players will feel that their decisions really matter.
C) In a limited way, yes. You can "date" all characters regardless of your gender, but their reactions will be different of course.
D) Enburn yes. You can learn it in the demo depending on your choices in the beginning of the game. As for other spells, I will still have to think about it. For Transio, right now my decision is no. There's a lot of factors to think about in terms of game mechanics and also lore wise. So I have to be careful about it.
Thank you very much for the words of encouragement too!
