Interface utilisateur du jeu de chiot sirène pastel sous-marine

A charming side-view underwater casual game start screen, rendered in a soft 3D cartoon style, designed like a refined children's web game interface. The scene depicts a bright seabed, with sunlight streaming through clear blue water, accompanied by floating bubbles, distant silhouettes of small fish, and a dreamy coral reef environment filled with rounded pink, purple, blue, and mint green corals, seagrass, shells, rocks, and sand. In the center-left of the image, a mermaid puppy character inspired by rescue dog cartoons floats happily underwater, with a dog face, sparkling large eyes, drooping ears, a small crown-shaped ornament on her head, and a fish tail instead of hind legs, facing forward with a cheerful expression. To the right stands a quirky candy-colored coral lighthouse, shaped like a pink and white shell tower, with a glowing lantern room on top, a pearl embedded in the roof, round shell windows, a small balcony, a purple door, and coral details at the base. Game UI elements are directly overlaid on the scene: two rounded white capsule buttons in the upper left corner, the first reading “Go to Lighthouse,” the second displaying “0/3”; and a circular white pause button with a pause icon in the upper right corner. Near the lighthouse, display 4 floating semi-transparent colored target rings around interaction points: a pink ring near the upper-middle window, a yellow ring near the upper-right lantern area, a light blue ring covering the lower-right shell window, and a ring with a white outline around a purple jellyfish in the lower-left center. 3 collectible shell pearl items are visible in the scene: a glowing golden pearl in an open shell in the center, a dark blue small pearl shell at the base of the lighthouse, and a red pearl shell placed on the UI panel at the bottom center. At the bottom center, place 3 rounded white operation prompt buttons, with the text: “Arrow Keys / WASD,” “Space / Enter: Drop Pearls,” and “Esc to Map.” Add a large semi-transparent rounded white panel behind the bottom operation buttons. The overall image should evoke a happy, safe, colorful, and magical feeling, with a high degree of refinement, soft depth of field, soft lighting, glossy toy texture, and a mobile or web game aesthetic suitable for children.
