Just finished played one time through. I have no idea of the possibility space from the branching dialogues but from what I experienced I think you expertly captured a feeling of consequences to choices and urgency that I don't get from other games. The game genuinely felt like the stakes are high and I had only one chance to make things right, even with the prior knowledge that I could have just saved and loaded the game and reset my mistakes.
The combat is fascinating to me and I think it was a great idea to have 3 effective pools to build from and attack on, which makes it not so trivially optimizable to build a deck around. Combine that with the strongly tied themes of debate behind the deck-based combat and I see a very strong base for a game here. I will eagerly await for further updates!
