About this game

Shell Harmonics is a match-3 game on the ocean floor where you swap adjacent shell tiles to line up three or more of a kind and clear them. Chaining cascades fills your harmony meter and triggers a resonance multiplier, while the depth-pressure gauge keeps climbing toward a structural failure you must outpace. Detonate tortoise tiles to break up the grid as you dive deeper for a higher score.
