Hi, Hayley,
Thanks for the great review!
Rest assured, the angels are *not* 'fluffy bunny good'.
<i>Scorn: The Second Book of Pandemonium</i> will detail the armies of Heaven in more detail, but in brief, they're worse than demons.
I'm glad you liked the system. I know that the d12 isn't commonly used, and I'm always a little nervous that people will be put off just because the game doesn't use a die (or a mechanic) that they're familiar with. It's great to hear that the d12 system worked for you.
I never thought about player resurrection, but that might be something to consider for future supplements/sourcebooks.
Thanks again!
