I'm glad you're enjoying the characters so far haha. I really try to make each of the mentors' personalities distinct and I'm glad that's coming through in the writing! I've heard a few people talk about how they want to base their MC off of Callen and Sonia's personalities - being the opposite or similar to them, and I'd love to have text in the game that references this.
And thanks, the interface is still a work-in-progress but I wanted to overhaul it a little for this update, it looked fairly basic initially.
