No, all in all you understand the game.
you loop you have "greet" AND "ignore" as proposals, and then it is not possible to choose between them, because these two are answers.
Ahh, that was intended. Some bad choices in design were made that I couldn't test out a lot. With more testing I could have made this happen sparsely or have given better instructions.
So if you choose greet-greet-greet-ignore then it loops you have to choose the same things you chose before, and the other similar choices are to confuse you, so you must still choose, in the same order (ignoring other cards in the middle), greet-greet-greet-ignore and choosing anything else will lead to a fail (e.g. greet-greet-greet-greet, or greet-ignore-greet-ignore). I hope this makes sense.
Thanks for testing it out!
