Please use Three.js to generate a **mobile-first game** with the theme "**Sift Heads World Act 1 - Mobile Edition**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** High-contrast "Stickman Noir" aesthetic. The color palette must be strictly limited: Grayscale (Black, White, various Greys) for the environment and characters, with **Blood Red (#FF0000)** reserved strictly for blood effects, danger indicators, and critical UI elements. * **Characters:** Create 3D Stickman characters using simple geometry (spheres for heads, thin cylinders for limbs). The Player character should be solid black with distinct accessories (e.g., white sunglasses or a red bandana). Enemies should be visually distinct (e.g., grey bodies with dark tactical gear). * **Environment:** An urban alleyway or rooftop scene. Use low-poly cubes for buildings, textured with simple concrete patterns. Incorporate volumetric fog or dark lighting to enhance the "noir" atmosphere. * **Effects:** * **Muzzle Flash:** Bright yellow/white point lights appearing briefly at weapon tips. * **Blood Particles:** Simple red square sprites that explode outward upon enemy death. * **Performance:** Use InstancedMesh for particle effects and repetitive environmental props (like trash cans or ammo crates) to ensure smooth 60fps performance on mobile devices. ### 2. Audio Requirements * **BGM:** A loopable, down-tempo urban hip-hop or trip-hop track with a heavy bassline and cinematic strings, evoking a "cool assassin" vibe. * **Sound Effects (SFX):** * **Gunshots:** Loud, crisp, and varied based on weapon type (pistol vs. assault rifle). * **Reload:** Mechanical clicking sounds. * **Impact:** A wet "thud" for body hits and a metallic "ping" for missed shots hitting the environment. * **UI:** Subtle "swoosh" sounds for menu transitions and a satisfying "cha-ching" or score tally sound when a mission is completed. ### 3. Gameplay Loop * **Core Mechanic:** A rail-shooter or cover-based shooter system. The camera moves automatically between cover points. When stopped at cover, the player engages enemies. * **Combat Logic:** * Enemies pop out from behind objects. * Player health decreases if they stay out of cover too long while enemies are firing. * **Headshot Mechanic:** Hitting the head sphere deals double damage and triggers a larger red particle effect. * **Progression:** Eliminate all enemies in the current "screen" to prompt the character to run to the next cover point. * **Victory/Defeat:** * **Win:** Complete 3 waves of enemies. Show a "Mission Accomplished" screen with accuracy stats. * **Loss:** Player HP reaches 0. Show a dramatic "Wasted" screen with a retry button. ### 4. Mobile Controls & Interaction * **Orientation:** Landscape mode (fullscreen). * **Aiming & Firing:** * **Left Half of Screen:** Touch and drag to move the crosshair (reticle). * **Right Half of Screen:** Tap to fire. Hold for automatic weapons. * **Reload:** A dedicated, large circular button (icon: bullets) in the bottom right corner (at least 64x64px). * **Cover System:** A "Take Cover" toggle button (bottom center). When active, the camera lowers, and the player is invincible but cannot shoot. Release to pop up and shoot. * **Feedback:** * **Haptic Feedback:** Trigger a short vibration (navigator.vibrate) on every gunshot and a longer vibration when taking damage. * **Visual Feedback:** The screen edges pulse red when low on health. The crosshair turns red when hovering over an enemy. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
