About the game
Tidekeeper
An idle game about a moonlit tide pool. Harvest pearls from the giant clam, raise plankton, shrimp, kelp, seahorses and moon jellies, ride the spring tide when it rolls in, then migrate the reef to start again stronger.
Pearls are a game resource. They aren't ggbucks and can't be exchanged for money or rewards. Nothing in this game earns or spends ggbucks.
