Resonance of the Ocean will allow players to immerse themselves in a leisurely and often meditative gameplay that is not burdened with complex tasks or tedious competitions. Here you can spend half an hour of your free time exploring the world around you in search of harmony with nature. At the center of this adventure is a girl who lives on the seashore. One day she went for a walk along a deserted beach, where all the events of this story will take place. Players need to listen to the sounds coming from the island opposite. As the waves pass, various objects will be washed up, from which you need to try to make a musical instrument.

As the plot of Resonance of the Ocean progresses, you will need to explore the coast, pick up and put various finds into your inventory, and try to combine them in the right way. At the lighthouse, using the improvised gadget you received, you will answer the distant echo. The heroine will comment on each thing found, giving players a hint on how to best use it. The gameplay will be accompanied by real-life sounds of the surf and other soothing sounds. The project offers hand-drawn 2D graphics with a top-down view and resembles an interactive cartoon in its design.
