About Tide & Tangle, from BoardGameGeek:
Tide & Tangle is a cheerful yet tactical game where players take on the roles of sea otters diving for valuable (and often tasty) sea treasures. But the ocean is never still. Navigate waves to stay away from the coast, wisely choosing your diving spots and how deep you wish to go. And hey, lending a helping paw might just make the ocean feel a little less lonely and a lot more fun!
On the surface, the game is simple: swim around the board, push your luck diving for treasures, or flip your otter on its back to raft, preparing for the challenges ahead. But if you want to score big and be the most joyful otter in the Pacific, you'll need sharp timing to ride those fresh waves just right: Tide & Tangle features a unique modular board system with moving wave tiles, requiring players to adapt to the ever-changing nature of the ocean.
