Please use Three.js to generate a **mobile-first game** with the theme "**Slopey: Infinite Neon Descent**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: High-contrast, futuristic "Neon Cyberpunk" aesthetic but simplified for mobile performance. The world should feel fast and sleek. * **The Ball (Player)**: A shiny, metallic sphere (standard material with high reflectivity) that emits a soft glowing trail. The trail should use a simple ribbon mesh or particle system to convey speed without heavy overdraw. * **The Track**: Procedurally generated, endless downhill slope composed of elongated rectangular platforms. * **Texture**: Use a dark, matte material (dark grey/purple) with glowing neon edges (cyan or magenta) to clearly define the playable area against the background. * **Geometry**: Low-poly geometry. The track should twist, turn, bank, and feature gaps. * **Obstacles**: Static red blocks or rotating barriers that kill the player on impact. * **Collectibles**: Glowing, floating diamonds or gems (low-poly icosahedrons) rotating in the air, surrounded by a subtle golden ring (torus) as seen in the reference. * **Background**: A deep gradient fog (Purple to Black) to hide the draw distance and create a sense of depth. A distant "sun" or light source at the horizon adds focus. * **Lighting**: Ambient purple light plus a directional light casting long, dramatic shadows. * **Mobile Optimization**: Use instanced mesh for repeating track segments and collectibles to keep draw calls low. Limit real-time shadows to the player area. ### 2. Audio Requirements * **BGM (Background Music)**: A fast-paced, driving Synthwave or Drum & Bass track (around 160-170 BPM). It should feel energetic and induce a "flow state." * **SFX (Sound Effects)**: * **Rolling**: A continuous, low-frequency hum that rises in pitch as speed increases. * **Jump/Landing**: A crisp "thud" with a slight metallic resonance when the ball hits the track after a gap. * **Gem Pickup**: A high-pitched, satisfying "chime" or "bling" sound (positive feedback). * **Game Over**: A digital "shatter" or "glitch" noise followed by a sudden silence. * **UI Clicks**: Soft, futuristic "bloop" sounds. ### 3. Gameplay Loop * **Core Mechanic**: The ball automatically moves forward with constantly increasing speed. The player's only control is steering Left and Right. * **Physics**: Arcade-style physics. Gravity is strong to keep the ball grounded, but lateral movement (steering) should be snappy and responsive, not floaty. Momentum is key—the ball should feel heavy but fast. * **Objective**: Survive as long as possible while navigating a randomly generated track that gets narrower and faster over time. * **Scoring**: * **Distance**: +1 point for every meter or platform survived. * **Gems**: +10 points (or currency value) for every gem collected. * **Fail State**: Falling off the edge of the track or colliding directly with a red obstacle results in an immediate Game Over and a "Restart" button. ### 4. Mobile Controls & Interaction * **Screen Orientation**: **Portrait Mode** (Vertical) is preferred for one-handed play, though the camera should be positioned slightly lower and closer to the ball to show the track ahead. * **Control Scheme (Touch)**: * **Hold & Drag**: Use a 1:1 screen-to-steering mapping. Touching anywhere on the bottom half of the screen and dragging left/right steers the ball. * **Alternative (Tap)**: Tap left side of screen to steer left, tap right side to steer right (less precise, drag is preferred). * **Camera Behavior**: The camera must follow the ball smoothly but with a slight "look ahead" offset so the player can see upcoming obstacles. When the ball speeds up, the camera should pull back slightly (increase FOV) to enhance the sensation of speed. * **UI/UX**: * **Score Display**: Large, legible font at the top center. * **Start/Restart**: Big, thumb-friendly button (at least 60px height) at the bottom center of the screen. * **Haptic Feedback**: Trigger a short vibration (using `navigator.vibrate`) when collecting a gem and a longer vibration upon death. **Please execute the code generation based on these specifications.** Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
