Create a **Flappy Bird-style pixel-art gameplay animation set entirely in San Francisco**, presented as authentic retro mobile game footage. A tiny pixel-art bird automatically flies from left to right while the camera remains fixed in a classic side-scrolling 2D perspective. The player keeps the bird airborne by repeatedly flapping upward while gravity constantly pulls it downward. Instead of the traditional green pipes, every obstacle should be unmistakably **San Francisco-themed** while preserving the exact same simple gameplay mechanic: each obstacle creates a narrow vertical opening that the bird must fly through without touching anything. Use obstacles such as: * Two steep San Francisco hills forming a narrow gap. * Victorian houses extending down from above and up from below. * Giant red sections of the Golden Gate Bridge creating openings between the towers and roadway. * Cable cars entering from the top and bottom of the screen. * Downtown skyscrapers forming tight passages. * The Transamerica Pyramid extending into the flight path. * Coastal cliffs surrounding a narrow opening. * Construction scaffolding creating rectangular gaps. * Giant redwood trees framing the flight path. * Fog banks partially surrounding openings while keeping the playable gap clearly visible. Every obstacle must function like a real Flappy Bird obstacle: **one clear opening, one required flight path, no alternate routes.** ### SAN FRANCISCO ENVIRONMENT Make the scrolling background unmistakably San Francisco. Include layered pixel-art scenery: **Foreground:** rooftops, streetlights, cable-car wires, fire escapes, trees, signs and passing architectural details. **Midground:** colorful Victorian houses, steep streets, cable cars, cafés, parks, dense neighborhoods and downtown buildings. **Background:** San Francisco Bay, Alcatraz, the Transamerica Pyramid, Salesforce Tower, rolling hills and the Golden Gate Bridge. **Sky:** bright California sunset colors, huge pixel clouds, drifting coastal fog, distant birds and subtle atmospheric animation. The scenery should continuously scroll from right to left while the bird remains around the left-center of the screen. ### GAMEPLAY The bird flies automatically forward. Each flap causes a quick upward movement followed by a smooth downward arc from gravity. The gameplay should be fast, simple and immediately readable. Show the bird successfully passing through multiple increasingly difficult San Francisco-themed gaps. Obstacle spacing should feel fair but challenging. Never allow the bird to fly around an obstacle. Every obstacle must extend completely from either the top or bottom edge of the playable screen, leaving only one intentional opening. The sequence should feel like genuine uninterrupted gameplay rather than a cinematic animation. ### BIRD ANIMATION Use a charming, simple pixel-art bird with a tiny 2–4 frame wing-flapping animation. Keep the bird's: * sprite design * proportions * colors * beak * wings * eyes completely consistent throughout the sequence. When flapping upward, slightly tilt the bird upward. When falling, gradually tilt the bird downward. ### SCORE Include a large retro pixel-number score centered near the top of the screen. Start at a low score and visibly increase it by one every time the bird successfully clears an obstacle: **3 → 4 → 5 → 6 → 7** Keep the UI extremely minimal. No menus, dialogue, instructions or unnecessary interface elements. ### PIXEL-ART STYLE Crisp handcrafted pixel art with visible individual pixels. Limited retro color palette. No 3D rendering. No realistic textures. No vector graphics. No motion blur. No anti-aliasing. No smooth painted edges. Everything should look intentionally created as pixel art. The visual quality should feel like a beautifully polished modern indie recreation of a classic 2010s mobile game. ### CAMERA Classic fixed side-view gameplay camera. No zoom. No camera rotation. No cuts. No cinematic angles. The bird maintains approximately the same horizontal position while the entire San Francisco environment continuously scrolls from right to left. ### AUDIO Use a simple catchy retro mobile-game soundtrack with light chiptune melodies. Add: * short flap sound on every wing beat * satisfying point sound whenever an obstacle is cleared * subtle cable-car bell sounds * distant city ambience * occasional seagulls * soft wind near the Bay Keep the music playful and addictive. ### OVERALL FEEL It should immediately read as: **“Flappy Bird, but the entire game takes place in San Francisco.”** Simple, addictive, funny and instantly recognizable. The city's architecture and landmarks should replace the traditional obstacle design without making the gameplay complicated. **Format:** 16:9 widescreen, continuous side-scrolling pixel-art gameplay, fixed camera, no cuts, retro game audio, minimal score HUD, no logos.
