IMAGE TYPE Polished mobile puzzle gameplay-direction reference, opaque portrait PNG, 9:16. One coherent frame, not a collage, presentation board, sprite sheet, store screenshot, device mockup, or concept sheet. SUBJECT Compass Shift, a distinctive flat 2D arrow-release logic game presented as a modern navigational instrument. A deep chart-blue instrument shell holds one pale sea-glass rectangular board well. A large low-profile circular compass bezel wraps immediately around and behind the board. The bezel has four unequal groups of cardinal ticks and a brass index notch, with a restrained visual cue that it has just rotated exactly one quarter-turn. Do not use letters or numbers on the compass. GAMEPLAY CONTENT Place 10 to 14 separate flat arrow tiles on a sparse orthogonal grid. Tiles are thin rounded lozenges or compact chart-marker plates with one large geometric arrowhead, colored in balanced signal coral, warm brass, and bearing teal. Color is decorative; every direction must read from the silhouette. Show exactly one coral arrow in the act of sliding straight out through one open edge aperture. All other arrows remain on the board, with their arrowheads coherently reoriented by the shared compass. Include one matte ink-blue static wall, one shutter-like phase-gated edge window with a cardinal tick cluster, and one patterned edge port with simple dot-dash marks. Keep the mechanic readable at thumbnail size. COMPOSITION AND CAMERA Fixed orthographic front view, perfectly flat 2D board, no perspective room, no isometric angle, no rotating whole board. Board uses about 75 percent of safe portrait width with generous negative space. The compass bezel is a signature object, larger than a status icon and spatially integrated with the board. Minimal icon-only undo, restart, help, and pause controls may sit outside the board, but no text of any kind. STYLE AND MATERIAL Premium editorial vector-like mobile-game art; modern charting instrument; calm, tactile, precise, and original. Opaque matte enamel, printed chart ink, crisp rounded geometry, shallow contact shadows used only to separate flat layers. Not photoreal. Not a nautical scene. Not a generic toy. PALETTE Deep chart field #071E2F, chart-blue shell #0E3550, pale sea-glass board #CFE3D9, ink bearing #173849, signal coral #EF6B5B, warm brass #C8A45D, bearing teal #2B9B91, warm sail highlights #F5F0E5, blocked berry used sparingly #A84656. No electric-neon glow. STATE CLARITY The releasing arrow follows one completely clear straight ray to its edge aperture. At least two remaining arrows have visibly different effective directions after the quarter-turn. Static wall, phase window, and patterned port are distinct through shape and pattern, not text or color alone. Show restrained motion arcs only on the shared bezel; never imply that the entire board freely rotates. NEGATIVE CONSTRAINTS No words, letters, numerals, captions, logos, watermark, badges, prices, UI labels, or fake store chrome.
