Echoes of Lumen

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Recreate "Echoes of Lumen" as a minimalist, stylized 3D environment viewer called "Arrival Beach · Environment Prototype." Make it a real-time Three.js-like scene filling the entire viewport, with no character avatar, enemies, collectibles, combat, score, timer, or win condition. The interaction is camera exploration only: provide orbit controls so the user can drag to look around the beach and scroll to zoom. Use damping/smoothing on the orbit camera, with a perspective view initially positioned above and to one side of the beach, looking toward the center. Constrain the camera to a close/far distance roughly equivalent to 9–48 world units and prevent it from going below the scene; the default framing should show a broad sandy shore in the foreground, turquoise water around it, and a hazy soft teal sky/horizon.

Build the scene from broad low-poly polygonal surfaces rather than detailed props. The main Arrival Beach is an irregular, wide roughly rectangular sand body around 30 units wide and 20 units deep, extending across the foreground. Give its shoreline an intentionally uneven zig-zag outline, with small angular variations along the edge. Use a pale warm sand material around #f2cc82, rough and nonmetallic, with flat shading. Add subtle procedural low-amplitude ripples/height variation across the sand and a very slight raised edge toward the rear, so the surface is faceted but nearly flat. Along the ocean-facing front edge, add a thin darker wet-sand lip following the irregular shore, in muted tan around #d9b879, also flat shaded. Behind the beach, add a soft low interior/island transition region with no objects or props, colored muted yellow-green around #b9c884, continuing upward toward the back of the scene.

Surround the land with an expansive shallow stylized turquoise ocean: use a very large, subtly irregular/wavy horizontal plane extending far into the distance, colored vivid cyan-turquoise around #28c7c7, slightly transparent and moderately rough with a small amount of metalness. Add a broad translucent lighter shallow-water band between beach and open ocean, around #58ddd2, to blend the shore into the water. The ocean should be visibly open beyond the island and should have only extremely subtle geometric wave undulation; do not add boats, rocks, vegetation, buildings, or other scenery. Animate the water almost imperceptibly with a slow rotation/drift so the scene remains tranquil.

Use a seamless soft fantasy sky: a pale teal/aqua background around #8bd8d5 with a large back-facing spherical sky dome, and atmospheric fog in a slightly lighter teal (roughly #9fe0dc) that fades distant surfaces. Light the scene brightly and softly with a cool/warm hemisphere-style ambient light and a warm pale directional sun from above/front-left. Use high exposure and gentle filmic tone mapping so the pastel colors appear luminous and washed-soft, with ambient shadows but no dramatic contrast. Keep materials matte, flat shaded, low-poly, and clean.

Overlay a fixed HUD above the canvas. At the upper-left, show large cream-white uppercase text with slight letter spacing and a soft dark teal shadow: "ECHOES OF LUMEN". Directly below it, in smaller uppercase widely spaced text, show "ARRIVAL BEACH · ENVIRONMENT PROTOTYPE"; on narrow screens this subtitle may wrap to two lines as in the reference. At the lower-right, show a rounded pill hint reading "Drag to look · Scroll to zoom" in translucent white text over a subtly dark translucent teal background, with a thin semi-transparent white border and a light blur/glass effect. The HUD must not block pointer input to the 3D canvas. Make the layout responsive, with the title inset approximately 22px from the left and 18px from the top and the hint inset approximately 22px from the right and 18px from the bottom. The overall presentation should match a calm pastel concept-art environment mockup: a nearly empty turquoise ocean, angular pale beach, distant island transition, hazy horizon, and restrained typography.
