Please use Three.js to generate a **mobile-first game** with the theme "**Jetpack Joyride Clone**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller using an Orthographic Camera. The art style should be **Cel-Shaded / Low-Poly Cartoon** to mimic the original game's vibrant 2D aesthetic while utilizing Three.js's 3D capabilities. Colors should be punchy (blues, yellows, hazard oranges). * **The Hero (Barry):** A stylized low-poly character wearing a blue suit and a metallic jetpack. * **Jetpack FX:** This is crucial. Create a continuous particle system that shoots "bullets" or "flames" downward when the player ascends. These particles should collide with the floor (visual only) for chaotic feedback. * **The Lab (Environment):** An infinite scrolling background (parallax effect). * **Layers:** Foreground (Action plane), Mid-ground (Lab walls, pipes, warning lights), Background (Distant machinery). * **Decor:** Yellow/Black hazard stripes on the floor and ceiling. Tiny, fleeing scientists (simple blocky meshes) running on the floor as non-interactive ambient details. * **Optimization Strategy:** * Use `InstancedMesh` for the coins to handle hundreds of objects efficiently on mobile. * Use Texture Atlases for environment segments. * Limit dynamic lights; bake shadows into textures where possible. ### 2. Audio Requirements * **BGM (Background Music):** A fast-paced, driving "Arcade Rock" track with heavy bass and retro synth leads. It should loop seamlessly and increase in tempo slightly as the game speed increases. * **Sound Effects (SFX):** * **Jetpack:** A rapid-fire "Rat-a-tat-tat" machine gun sound or a roaring thruster sound that plays *only* when the screen is touched. * **Coins:** A satisfying, high-pitched "Ding" or "Ching" with slight pitch variation to prevent monotony. * **Hazards:** An electrical "Buzz/Hum" for Zappers; a "Siren + Whoosh" for incoming missiles. * **UI:** crisp "Click" sounds for menus and a "Thud" or "Zap" sound for Game Over. ### 3. Gameplay Loop * **Core Mechanic:** The game is an Endless Runner. The character runs automatically to the right. * **Physics Logic:** * **Gravity:** Constantly pulls the character down. * **Thrust:** Holding the screen applies upward vertical velocity. Releasing lets gravity take over. The character runs on the ground when not flying. * **Obstacles:** * **Zappers:** Electric fields (horizontal, vertical, or diagonal) appearing at random heights. * **Missiles:** A warning exclamation mark `!` appears on the right edge of the screen for 1 second, followed by a missile shooting across a specific lane. * **Collectibles:** Floating Gold Coins arranged in patterns (waves, lines, sinusoids). Collecting them increases the "Money" score. * **Progression:** The scrolling speed increases gradually every 30 seconds. * **Win/Loss:** No win condition (Endless). Loss occurs upon collision with a Zapper or Missile. Show a "Distance Traveled" result screen. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Forced **Landscape** mode. * **Control Scheme (One-Button):** * **Global Touch Area:** The entire screen is the input button. * `touchstart` / `mousedown`: Activate Jetpack (Ascend + Fire Particles). * `touchend` / `mouseup`: Deactivate Jetpack (Descend / Fall). * **UI Layout:** * **HUD:** Distance counter (Top Left), Coin counter (Top Right). Large, legible fonts with outlines. * **Pause Button:** Top Right corner (at least 44x44px hit area). * **Game Over Screen:** Large "Retry" button centered on the screen for easy thumb access. * **Feedback:** * **Camera Shake:** Slight screen shake when a missile hits nearby or the player dies. * **Haptic Feedback:** Trigger `navigator.vibrate(50)` on death or collecting a special power-up (if implemented). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
