5 stars for the audio. The whole table was singing.
We printed the ruleset, and realized a little late that you should have printed one set of cards per player. So we had to craft a few extra pirates, and share the rest of the cards between us. It's a great idea, fast-paced and chaotic. We didn't have the chance to try which number of player and cards works best, but that's something a bit of playtesting certainly would iron out.
I like that it is not clear from the progress of the game, who is winning in the end: Suddenly you are left with five cards in your hand, or the other player has the better choice of symbols.
Some balancing might be needed: In our games it was slightly too easy for the shantyperson to put double symbols into the deck, so we needed many rounds (and some extra pirates) to bring the game to an end.
I also wonder if the cards could carry full verses or half verses instead of single words to make the song more coherent.
