Background and Worldview: In the ethereal coral reefs of the deep sea, the mermaid princess’s pearl necklace has broken, its pearls scattered among anemones and shipwrecks. Players match pearls of the same color to help the mermaid reassemble the necklace and restore harmony to the ocean concert.

Core Gameplay: A match-3 style game, but the pearls are located in dynamic 3D ocean currents. The connection may be delayed due to the current’s movement, requiring players to complete the match within a time limit. There are “deep-sea darkness” areas that need to be illuminated using lighting items.

Features: A tide system where real-world tide times affect game difficulty (matching time is reduced during high tide). Collect pearl illustrations.

Visuals and Sound Effects: A gradient from deep blue to turquoise, with plankton glowing and schools of fish swimming by. The ethereal melody of a mermaid and the sound effects of flowing water.
