Please use Three.js to generate a **mobile-first game** with the theme "Cipher Crossword Logic Puzzle". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist "Newspaper" aesthetic but modernized with 3D elements. Use an Orthographic Camera to maintain a clean, flat puzzle look while preserving the 3D depth of the tiles. * **Board**: The grid should consist of 3D rounded cubes. * **Empty Tiles**: Off-white/Cream color. * **Blocker/Wall Tiles**: Dark Grey or Black (non-interactive). * **Selected Tiles**: Highlighted with a soft blue or gold outline/glow. * **Letter Tiles**: When a letter is placed, render 3D text (TextGeometry or high-res texture) on top of the tile. * **Optimization**: Use `InstancedMesh` for the grid tiles to ensure 60FPS on mobile devices, as crossword grids can have many cells. Use a simple directional light with soft shadows to give depth to the tiles. ### 2. Audio Requirements * **BGM**: A calm, intellectual, looping track. Think "Coffee Shop Lo-Fi" or "Soft Classical Piano" to aid concentration. * **Sound Effects**: * *Tile Select*: A soft "paper tap" or wooden click sound. * *Letter Placement*: A satisfying mechanical typewriter "thwack" sound. * *Success*: A gentle chime or chord when a word is fully formed correctly. * *Level Clear*: A short, uplifting jingle. ### 3. Gameplay Loop * **Core Mechanism (The Twist)**: Unlike standard crosswords, there are **no text clues** (e.g., "1 Down"). This is a logic/substitution puzzle. * The code should pre-generate a valid crossword solution (or use a hardcoded level array for this demo). * **Linkage System**: Behind the scenes, all instances of the same letter (e.g., all 'A's) are linked. * **Player Action**: The player taps an empty white tile. The game highlights **that tile AND all other tiles** on the board that share the same hidden letter. * **Input**: The player selects a letter from the virtual keyboard. All highlighted tiles are simultaneously filled with that letter. * **Validation**: * Check for victory when the board is full. * Optional: Highlight conflicting words in red if the dictionary logic is simple, otherwise just check the final board state against the solution. * **Difficulty**: Implement a "Beginner" mode for this prototype (smaller 10x10 grid). ### 4. Mobile Controls & Interaction * **Layout & Orientation**: * **Portrait Mode Support (Priority)**: Place the 3D Board in the top 60% of the screen and the Virtual Keyboard in the bottom 40%. * **Responsive**: The camera zoom should adjust automatically so the grid fits within the width of the phone screen. * **Touch Controls**: * **Raycasting**: Implement precise raycasting for touch events on the 3D tiles. * **Virtual Keyboard**: Create an HTML/CSS overlay or 3D UI buttons at the bottom of the screen for the letters A-Z. Keys must be at least 44x44px for touch accessibility. * **Gestures**: Allow one-finger panning to move the board and two-finger pinch to zoom if the grid is larger than the screen. * **Feedback**: * **Haptic**: Trigger `navigator.vibrate(10)` on a successful letter placement if supported. * **Visual**: When a letter is placed, play a small "pop" or "flip" animation on the affected tiles. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
