Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Letter Dimensions**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Low-poly, "Cute" aesthetic with a pastel color palette (soft pinks, blues, yellows, greens). The look should be clean and legible, similar to casual mobile puzzle games. * **Core Models:** * **Blocks:** Simple 3D Cubes (`BoxGeometry`). Each cube face should display a clear, cartoon-style Alphabet Letter (A-Z). * **Platform:** A circular turntable base (Cylinder) where the block stack rests. * **Background:** A subtle, static abstract background (e.g., blurred falling letters or a soft radial gradient) that does not distract from the gameplay. * **Performance Optimization (Mobile):** * Use **Texture Atlases** for the letters to reduce draw calls. * Implement **InstancedMesh** for the cubes if possible, as there are many identical geometries. * Limit real-time shadows; use baked lighting or simple ambient occlusion to differentiate block depth. ### 2. Audio Requirements * **BGM (Background Music):** A relaxing, lighthearted, and looping track using instruments like marimba, soft piano, or pizzicato strings to fit the "Cute" tag. * **Sound Effects (SFX):** * **Select:** A soft "click" or "bloop" sound when a block is tapped. * **Match/Success:** A satisfying "pop" or harmonic chime when two blocks are successfully cleared. * **Error:** A low-pitched "thud" or shake sound if a player tries to select a blocked tile. * **Win:** A short, celebratory fanfare. * **Timer Warning:** A ticking clock sound when the last 10 seconds remain. ### 3. Gameplay Loop * **Mechanic (3D Mahjong):** * The game spawns a 3D stack of cubes based on a grid pattern (Level Data). * **Matching Rule:** The player must select two blocks with the **same Letter** (Color does not matter). * **Constraint (The "Open" Rule):** A block can only be selected if it has at least **two adjacent sides free** (left, right, top, front, or back). Blocks trapped inside the stack cannot be clicked. * **Win Condition:** Clear all blocks from the platform before the timer runs out. * **Lose Condition:** The timer reaches zero. * **Visual Feedback:** When matched, the cubes should vanish with a shrinking animation (`scale.set(0,0,0)`) and a small particle burst. ### 4. Mobile Controls & Interaction * **Camera/Rotation:** * Primary: **One-finger horizontal drag/swipe** to rotate the turntable (orbit the camera around the stack). * Secondary: On-screen arrow buttons (Left/Right) at the bottom of the screen for accessibility (as per original game description). * **Selection:** * Use `Raycaster` on `touchstart` events for immediate response. * **Highlighting:** When a valid block is tapped, it must glow or have a bright outline to indicate selection. If a second block is tapped: * Match: Remove both. * Mismatch: Deselect first, select second (or clear selection). * **UI Layout:** * **Top:** Level counter and Countdown Timer (large, legible font). * **Bottom Right:** "Hint" button (highlights a valid pair) and "Restart" button. * Ensure all buttons have a minimum hit area of **44x44px** for touch friendliness. * **Haptic Feedback:** Trigger a short vibration (`navigator.vibrate(50)`) on successful matches if supported by the device. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Mechanics

Matching Rules

Open Block System

Only "open" blocks can be matched - meaning they must have at least two free adjacent sides. This spatial requirement adds a layer of strategy, as you must carefully consider which blocks to match first to keep other blocks accessible.

3D Rotation Feature

Use the intuitive arrow controls to rotate the entire structure, revealing hidden blocks and new matching opportunities. This rotation mechanic is essential for spotting all available matches and planning your strategy.
