Thank you for leaving such a thorough comment, and for giving some of the games a try! I hope you play some of the multiplayer ones sometime, or try the ghazal one with another person -- as you've pointed out, it doesn't work very well when you play it alone, and much of the fun of the deck is in using it with others. (I threw in the Solitaire game just so prospective players could realize that there are ways to play with it by themselves. Incidentally, the way you ended up playing it is the way I hoped people would!)
In any case, I really appreciate your feedback on the rules! "Fish" was adapted from this website and "Pyramid" from this one, but the rest I'd learned from others I'd played cards with in person. I was trying to keep the instructions within the limits of a single page, so I was banking on my audience having some prior familiarity with them (at least enough to recognize to which classic game each set of rules corresponded if they felt puzzled, and to know J = 11, Q = 12, K = 13). I'm sorry for any confusion/frustration because of that! I will definitely run the "Ghazal" game through more tests and watch some of my friends play it to figure out where the unclarity lies. I'm curious -- what rules did you come up with when you played it to make it work for you?
As for my use of "cohere" in the instructions: In future versions, I will consider making it clearer that I mean verbal coherence, but I also wanted it to be vague enough for people to put, say, "passion" and "rapture" together and for this to feel legitimate (even though this is not a coherent set of words without an "and" inserted between them). I wanted the deck to be seen as an occasion for players to negotiate the meanings of different terms and the ways they might go together.
Your suggestion to make my own cards is a great one, and I hope I can once I have more time! I also hope I can someday make a digital version where players can save/use decks that have words of their own choosing, but I still need to get the coding chops for it...
