Please use Three.js to generate a **mobile-first game** with the theme "**Meow Market 3D**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** * **Style:** Low-poly "Kawaii" aesthetic with unlit or toon-shaded materials to mimic the flat, clean 2D art style of the reference image. Bright, pastel color palette (sky blues, soft browns, vibrant vegetable colors). * **Camera:** Fixed Isometric perspective (orthographic camera) to simulate the classic tycoon/shop management view, optimized for mobile screens. * **Characters:** * **Player:** A cute, round, white tabby cat (primitive shapes: spheres/capsules) stationed behind a wooden counter. * **Customers:** Varied animal spheres (Pandas, Orange Cats, Blue Whales, Dogs) that spawn off-screen and approach the counter. They should have simple "bouncing" idle animations. * **Shop Elements:** A wooden market stall with 3-4 visible crates. The crates display 3D icons of vegetables (Carrots, Tomatoes, Lemons, Eggplants). * **Lighting:** Ambient light (intensity 0.8) combined with a soft Directional Light to cast soft, diffuse shadows (not harsh). * **Optimization:** Use InstancedMesh for vegetables and repeated crates to ensure 60fps on mobile browsers. Limit polygon count per character to <500. ### 2. Audio Requirements * **Background Music (BGM):** A relaxing, looping "Bossa Nova" style track with soft flute melodies, light percussion, and upright bass. It should feel cozy and upbeat. * **Sound Effects (SFX):** * **Harvesting/Matching:** A crisp, satisfying "pop" or "bubble" sound when vegetables are clicked/collected. * **Sale Success:** A "cha-ching" register sound combined with a happy "Meow" sound. * **Customer Arrival:** A soft doorbell chime. * **UI Interaction:** Soft wooden "clack" sounds for button presses. ### 3. Gameplay Loop * **Core Mechanics (Hybrid Tycoon/Puzzle):** * **The Vegetable Field (Puzzle Layer):** At the bottom of the screen (or overlay), there is a grid of vegetables. The player must tap connected groups of same-colored veggies (Match-2 or Match-3 mechanics) to "harvest" them into the inventory. * **The Shop (Management Layer):** Customers line up at the counter requesting specific items (e.g., "2 Carrots"). * **Fulfillment:** If the player has harvested enough stock, the cat automatically hands over the item, gold is earned, and the customer leaves happy. * **Progression:** * Earn gold to unlock new crate slots (more variety). * Unlock "Golden Tools" that clear larger areas of the puzzle grid instantly. * **Victory/Failure:** * **Victory:** Endless high-score mode or reaching a daily profit quota. * **Failure:** If customers wait too long (patience meter runs out), they leave angry, and the shop reputation drops. ### 4. Mobile Controls & Interaction * **Orientation:** **Portrait Mode** (Vertical) is mandatory for one-handed play. * **Touch Controls:** * **Tap to Harvest:** Raycasting on the puzzle grid to detect taps. The touch area for each vegetable should be slightly larger than the visual model to forgive imprecise taps. * **Drag & Drop (Optional):** Allow dragging harvested veggies to customers for a more tactile feel, or keep it automatic for simplicity. * **UI Layout:** * **Top:** Shop sign, Day counter, Gold count (Large, readable font). * **Middle:** The 3D Shop view (Cat, Counter, Customers). * **Bottom:** The Puzzle Grid (interactive zone). Buttons must be at least 44x44px. * **Feedback:** * **Haptic:** Trigger a light vibration (`navigator.vibrate(10)`) when a successful match is made or a sale is completed. * **Visual:** Floating text numbers (+10 Gold) and particle confetti (star shapes) exploding from the customer upon a successful sale.
