I can't playtest this game, so I will have to make some guesses for my ratings.
It's an interesting concept, but I think the document could be organized better to showcase what it's all about. The sections are split by slightly different header and sub-header sizes, which makes it difficult to parse though quickly or to use as a reference if printed. A different way to indicate when a new concept is being discussed would help organize things a bit. Since the rules are fairly simple, an example play session and maybe a few more images could help new players visualize how this works.
