The rules themselves have some typoes and such – did you want those identified?

I had trouble with the abstraction layer. You shoehorned things into the music paradigm so hard that it makes my ears bleed. How the “chords” translate into play is just so abstract that it’s like Vancian magic or the early Final Fantasy fights – things happen which resolve in your favor or not, but while they look pretty it’s not at all clear what you are doing. In other words, the explanations show how the mechanics work but not why you would want to play with them.

Eight frets … interesting but with the conceptual linkage to guitar, most of the effective “chords” are unplayable and make no sense. Besides, chords are formed across STRINGS; most guitars are either six or twelve strings (and with 12 strings, they are tuned in pairs). (Yes, I am nerdgassing here.)

It’s either too much, or too little, tied into music at this stage, IMO.
