The dive with Shy was both neat and disappointing: since I just showed up at Shy's boat unannounced, we had no plan. Me being inexperienced, I was hoping Shy would take the lead. He did, and we swam through some stuff, but we had no idea WHAT to do since there are no real objectives in this game. It really seems like it would work better if the two players are going to the same new area together and exploring it gradually. I could imagine the Mermaid Caves being awesome with two people, as the limited communication would work ("Look at this!" "OK." "Wait!" "Follow me."). For just a "drop in, let's swim hoser" type situation, it is not really workable.
