Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Pull the Pin". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** A "Hyper-casual" aesthetic with a clean, minimalist look. Use a fixed **Orthographic Camera** to present the game board as a 2D plane with 3D depth (2.5D). * **The Container:** Create a glass or transparent acrylic flask/board shape (hourglass or funnel style) with wooden or metallic borders. The front face should be transparent to see the balls inside. * **The Balls (Critical):** * Use `THREE.InstancedMesh` to render hundreds of small spheres efficiently (essential for mobile performance). * **Color Logic:** Balls come in two states: **Colored** (Rainbow, Gold, Red) and **Grey** (Colorless). * **Texture:** High gloss, plastic material (MeshStandardMaterial) that catches the light to emphasize roundness. * **The Pins:** Long, metallic rods with distinct, bright neon green circular handles (easy to identify as interactive). They must act as static physics colliders blocking the path. * **Lighting:** Soft Ambient Light coupled with a Directional Light casting subtle shadows downwards to give depth to the piled-up balls. * **Background:** A neutral, clean radial gradient (grey to white) to ensure the colorful balls pop. ### 2. Audio Requirements * **BGM:** A relaxing, low-tempo "thinking" track. Soft marimba or electric piano, repetitive but not annoying, creating a "Zen" puzzle atmosphere. * **Sound Effects (SFX):** * **Pin Pull:** A distinct metallic "slide" or "shing" sound. * **Ball Collision:** High-pitched, subtle "clacking" sounds (ASMR style) when balls collide or flow heavily. * **Color Mixing:** A magical "chime" when a grey ball turns into a colored ball. * **Success:** A cheerful upward arpeggio when balls enter the bottom pipe. * **Failure:** A dull thud or "womp-womp" sound if balls fall off-screen. ### 3. Gameplay Loop * **Physics Simulation:** Implement a performant physics engine (like `Cannon-es` or `Matter.js` adapted for Three.js) where gravity is the primary force. Balls must behave like a granular fluid (piling up, tumbling). * **The "Color" Mechanic:** * If a **Colored Ball** touches a **Grey Ball**, the Grey Ball must visibly transform into a Colored Ball. * **Win Condition:** Only *Colored* balls can enter the bottom pipe. If all required balls reach the pipe (100%), the level is passed. * **Fail Condition:** If a *Grey* ball enters the pipe, or if balls are spilled outside the container (e.g., if a "Trap" mechanic is added later), the level fails immediately. * **Pin Mechanics:** Pins separate chambers. Pulling a pin removes the collider, causing the balls above to fall due to gravity. ### 4. Mobile Controls & Interaction * **Touch Controls:** Use `THREE.Raycaster` to detect touches. * **Action:** The user drags or taps the circular handle of a pin to "pull" it out. The movement should follow the direction of the pin (linear sliding). * **Screen Orientation:** Portrait mode (Vertical) is mandatory to accommodate the vertical flow of gravity and the flask shape. * **UI & Feedback:** * **Haptics:** Trigger `navigator.vibrate(20)` when a pin is successfully pulled. * **Progress Bar:** A UI overlay at the top showing "Balls Collected / Total Required". * **Touch Area:** Ensure pin handles have an invisible hit-box slightly larger than the visual model (min 44px equivalent) to be thumb-friendly. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Pull the Pin is a captivating physics-based puzzle game that combines simple mechanics with mind-bending challenges. Your mission is deceptively simple: guide every ball into the designated pipe by pulling pins in the correct sequence. However, as you progress through hundreds of levels, you'll discover that success requires careful planning, precise timing, and strategic thinking.

The game features a clean, minimalist design with colorful balls and wooden structures that create an engaging visual experience. Each level presents a unique puzzle where physics rules determine the outcome of your decisions.

Core Features

Physics-Based Gameplay

Every ball movement follows realistic physics principles. Gravity, momentum, and collision detection create authentic interactions that make each level feel dynamic and unpredictable. Understanding how balls will roll, bounce, and fall is crucial for success.

Color Mixing Mechanics

Many levels introduce colored paint that transforms white balls as they pass through. You'll need to ensure balls acquire the correct colors before reaching their destination pipes. This adds an extra layer of strategy as you plan the optimal path for each ball.

Progressive Difficulty

Starting with simple single-pin scenarios, the game gradually introduces: - Multiple pins requiring specific removal sequences - Color-changing mechanisms - Obstacle avoidance challenges - Multi-stage puzzles with complex interactions

Brain Training Benefits

Pull the Pin exercises critical thinking skills including: - Spatial reasoning : Visualizing ball trajectories and physics interactions - Sequential planning : Determining the optimal order for pin removal - Problem-solving : Finding creative solutions to seemingly impossible puzzles - Pattern recognition : Identifying recurring puzzle structures and solutions

Gameplay Mechanics

Each level presents a contained environment with balls held in place by strategically positioned pins. Your task is to analyze the setup and determine which pins to remove and in what order. Some key considerations include:

  • Pin Dependencies : Some pins support others, so removal order matters
  • Color Requirements : Balls may need to pass through colored areas before reaching pipes
  • Obstacle Navigation : Avoid bombs, spikes, and other hazards that can destroy balls
  • Timing Elements : Some puzzles require precise timing for optimal solutions

Operation Guide

The controls are intentionally simple to keep focus on the puzzle-solving aspect:

  • Mouse Click : Click on any green pin to remove it from the structure
  • Observation : Study the level layout before making your first move
  • Planning : Consider the consequences of each pin removal
  • Experimentation : Don't be afraid to restart levels and try different approaches

Pro Tips for Success

  1. Analyze First : Always examine the entire level before pulling any pins
  2. Work Backwards : Start by identifying where balls need to end up, then trace back the required path
  3. Consider Physics : Think about how balls will bounce, roll, and interact with obstacles
  4. Color Strategy : Plan the color-mixing sequence carefully to achieve required ball colors
  5. Patience Pays : Some levels require multiple attempts to discover the optimal solution
