Hello Peter,
You can watch the game being played by Wil Wheaton and friends at Geek & Sundry:

There are I believe some interviews too... BHH is on that page and you can click on the correct video to watch the game being played.
Your game is VERY "different". But it reminds me of BHH because of the "Traitor" mechanic where "something" happens and then the game is out-of-whack and players are scrambling to defeat the "Traitor" while trying to ensure that they don't die in the process.
So it's got a 2-Phase system much like Axis Mundi (AM). AM is players race to the middle and one (1) player emerges as an Angel or Demon. And then the play style changes. Well BHH does the exact thing. Except ONE (1) of the players is a Traitor and has lured the others to be sacrificed.
Anyhow no worries about the "ideas". Just wanted to share some insights into how to make the game LESS "abstract" and more defined. I don't expect you to change the entire game. Just pointed out some things to consider.
Cheers!
I found the BHH Geek & Sundry video on YouTube at the following addresses:

Yeah, definitely a different vibe (and gameplay) than I was going for, but interesting (and fun!) design.

Instead of your Angel/Demon vs. Opponents endgame idea, what do you think of the following idea I came up with: the game gradually tips the scales in the Angel/Demon’s favor using a leveling mechanic. The first Angel/Demon has the powers as they are right now. The second Angel/Demon gets a six-card hand limit instead of the normal five. The third Angel/Demon gets the same, plus a Scrounge (retrieving a card of their choice from the discard pile). The fourth gets a seven-card hand limit and a Scrounge. The fifth gets the same seven-card limit and 2 Scrounges, while the sixth automatically wins the game.
A shorter version might be better: the second Angel/Demon gets a 6 card hand limit and a Scrounge, the third gets a 7 card hand limit and 2 Scrounges, and the fourth automatically wins.
