Hi! Good video, I used it to refresh the rules before teaching them. I think there is an error around 13:50. The second scuba diver would only pick the treasure in the third row, because the one in the second was already picked up by the first scuba diver. The rulebook doesn't specify but there is a question about this matter in boardgamegeek where It has been said that each treasure is only picked up once, no matter how many scuba divers ascending through the same card.
This is one of those games that looks exciting, then they start to explain the rules and your eyes glaze over lost in colors, cards, yadda yadda, and 30 minutes later NO clear strategy has been painted or how to play the turns. *Yawn*
Please work on planning out your teach a little more. Your presentation was difficult to follow. It felt like you threw out all the rules, but you yanked so many cards off of the tableau and replaced them with others, it was impossible to distinguish between moves that were just to give an example and moves that would happen in normal play. I could tell whether all players would be adding their cards to the tableau or whether each player builds their own tableau. You never explained that. Finally, may I suggest that you begin by describing the object of the game and then start talking rules, but start with high level objectives, then work your way down to details. I don’t mean to put you down. Just trying to give feedback since you clearly take this channel seriously.
