Monkey Mart - Idle Supermarket Management Game - Simulation Game

Please use Three.js to generate a **mobile-first game** with the theme "**Monkey Mart Tycoon**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Create a vibrant, Low-poly, cartoonish 3D world. The aesthetic should be clean and colorful, similar to modern hyper-casual games. Use flat shading or toon shading to keep the look friendly and performance-light. * **Characters**: * **Player**: A cute, Low-poly monkey character wearing blue overalls (animated with idle, running, and carrying states). * **NPCs**: Simple customer monkeys and sleeping employee monkeys (use basic scaling or color variations to distinguish). * **Environment**: A supermarket layout on a grassy or tiled ground plane. Key structures include: * **Production Plots**: Patches of soil for growing crops (Bananas, Corn). * **Shelves/Stands**: Wooden or plastic racks for displaying products. * **Processing Machines**: Blocky machinery representations (e.g., a Microwave or Blender) for converting raw goods. * **Cash Register**: A distinct desk with a cash pile visual. * **Performance Optimization**: * Limit polygon count for all models (Low-poly is essential). * Use instanced mesh rendering for repetitive items like crops, stacked products, and cash bills to ensure 60FPS on mobile devices. * Use a single shared texture atlas for colors to minimize draw calls. ### 2. Audio Requirements * **BGM**: A jaunty, looping marimba or ukulele-based tropical track. It should be upbeat, repetitive but not annoying, fostering a "busy but happy" atmosphere. * **Sound Effects (SFX)**: * **Pop/Plop Sound**: When harvesting crops or placing items on shelves. * **Cash Register "Cha-Ching"**: A satisfying coin sound when collecting money. * **Footsteps**: Soft, rapid tapping sounds corresponding to the monkey's running speed. * **Upgrade/Unlock**: A rising chime or fanfare sound for positive reinforcement. * **Employee Snore**: Comical "Zzz" sound for sleeping workers. ### 3. Gameplay Loop * **Core Mechanic (Stack & Dash)**: * The player controls the monkey to run into **Crop Fields** to automatically harvest and stack items on their back (visualize a growing stack of items trailing the player). * Run to **Shelves** to automatically offload items for customers. * Run to the **Cash Register** to collect accumulated money from satisfied customers. * **Progression**: * Use collected money to unlock new zones (Unlock Zones appear as grayed-out squares on the floor with a price tag). * Unlockables include: New crop types (e.g., Corn, Peanuts), processing machines (e.g., Peanut Butter Maker), and hiring staff. * **Staff Management**: Hired employees will automate harvesting or shelving but will occasionally fall asleep. The player must run near them to wake them up. ### 4. Mobile Controls & Interaction * **Joystick Control**: Implement a responsive **Floating Virtual Joystick**. Anywhere the user touches on the screen becomes the center of the joystick. * **Visual Feedback**: Show a translucent circle UI under the finger. * **Physics**: The character movement should be snappy but have slight inertia (arcade physics) to feel good to control. * **Portrait/Landscape**: The game should be responsive, but prioritize **Portrait Mode** for one-handed playability. Camera should be an isometric top-down view (approx 60-degree angle) following the player smoothly. * **Interaction Zones**: No buttons for gameplay actions. All interactions (Harvest, Place, Buy, Collect) trigger automatically via **Collision/Proximity Triggers**. * Add a circular progress bar or visual "filling" effect when standing on a "Buy Zone" to prevent accidental spending. * **UI Feedback**: * Display a clear "Money Counter" at the top center. * Use floating text (+10$) popping up from the register when money is collected. * Haptic Feedback (Vibration) on collecting cash or unlocking a new upgrade (if supported by the browser API).
