The tide keeps draining out of the pool. Merge fast enough to hold it back, and see if you can grow plankton all the way into a leviathan.
About
Drop sea creatures into a glass tidepool. Two of the same creature merge into the next size up, through eleven creatures from plankton to a leviathan.
The water level keeps dropping, and each merge raises it again. If a creature stays above the water for five seconds, the run ends. A run takes about two minutes.
Each merge plays a note, and chains of merges play short tunes. The creatures you raise move to your reef, which earns pearls while you're away. You can spend pearls on charms, bigger reefs and decorations. There are five zones, each with its own twist.
