The tutorial is pretty good. I'm not fond of the AI. I think it's a hard game to do AI for since there are all those trading you're supposed to do. In real life, you usually can just say "who has a green bean they want to trade with me?" and then figure out what they want for it. With this app, first you have to figure out what the AI has and then figure out what they want (other than the beans they played). I think it's worth it for 0.99 though.
