Hi and thanks for the notes.  I will definitely plan on making those changes.

Definitely an example of the challenge pool mechanic, since it is a little different than most dice systems I've seen.

To answer your question here, I kind of imagined it like rolling both pools and matching up same dice to cancel each other out.  Of course, when I played with limited dice, I just kept track of the challenge pool's numbers and then rolled my own dice 1 or 2 at a time until I reached my cap and kept track of the numbers while doing so.  Less thematic, but it worked.  I'll include both methods, since I can't expect folks to have like 13+ six sided dice lying around.

On the harmonizing topic, I've been told that things make perfect sense in my noggin, but I often don't form the appropriate connections when I put pen to paper.  Looking over it, I also see that I haven't been super clear about that.

To answer your second question: The molting tore people's spirits from their bodies and made them phantoms.  I imagined in my head that some spirits (or their memories) were tied up inside objects.  Like benevolent phantoms or parts of them that remained connected to the world and their person-hood.  So, harmonizing with those memories was a way to pacify them from being frightened or connect with their thought patterns enough to be able to hold the object without it reacting negatively to you.

One movie this system drew inspiration from was Final Fantasy: The Spirits Within.

I hope my answers to your questions were adequate.

On that note, overall, thanks for taking a look at my game.  Once the jam concludes, I plan to tackle these things and create a post-jam version with a slightly higher word-count with some gameplay examples, lore, thematically placed flavor text, and maybe an illustration here or there.
