Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "What's The Difference?". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** High-saturation, casual "Juicy" aesthetic similar to King or Voodoo games. The background should be a dynamic 3D scene (e.g., a slowly rotating gradient sphere or floating soft particles in a pink/red palette) to replicate the screenshot's energetic feel, rather than a static CSS background. * **Image Planes:** Create two `THREE.Mesh` planes (PlaneGeometry) to display the "Photo Hunt" images. * **Responsive Layout:** Implement a logic to switch layout based on aspect ratio. * **Portrait (Mobile):** Stack images vertically (Top/Bottom). * **Landscape (Desktop/Tablet):** Place images side-by-side (Left/Right). * **Assets Generation (Procedural fallback):** Since external assets might not load, generate the "images" programmatically using HTML5 Canvas textures within Three.js: * Draw a grid of green apples (circles). * In the Right Image, change **one** apple to Red. * In the Left Image, keep all apples Green. * **Particles:** Implement a `THREE.Points` system for: * **Success:** A burst of stars/sparkles when a difference is found. * **Click:** A small ripple effect where the user touches. * **UI Overlay:** Use HTML/CSS overlay for the HUD (Score, Timer, Remaining Differences count) with a "Bubbly" font style to match the playful theme. ### 2. Audio Requirements * **BGM:** A relaxing, looping "Bossa Nova" or "Elevator Music" style track (acoustic guitar + light percussion) to encourage focus without stress. * **Sound Effects (SFX):** * **Correct Tap:** A high-pitched, satisfying "Ding" or "Chime" (Major key). * **Wrong Tap:** A dull, low-pitched "Thud" or "Buzzer". * **Win:** A short fanfair/trumpet sound. * **Hint Used:** A "shimmer" sound. ### 3. Gameplay Loop * **Core Mechanism:** * The player can click/tap on *either* the Top or Bottom image. * The game must map the `(x, y)` coordinates of the tap on one plane to the corresponding location on the other plane. * **Validation:** Check if the tap coordinates collide with a defined "Difference Zone" (bounding box of the Red Apple). * **Success Logic:** * If correct: Spawn a Green Circle outline on *both* images at that location. Lock that difference so it cannot be clicked again. Decrement "Remaining" counter. * Win Condition: All 5 differences found. Trigger confetti particle explosion. * **Failure Logic:** * If incorrect: Shake the camera slightly (screen shake effect) and show a temporary Red "X" mark. Decrease the time limit by 5 seconds (Time Penalty). * **Hint System:** A button that, when clicked, creates a spotlight effect (shader or pulsing circle) near an unfound difference. ### 4. Mobile Controls & Interaction * **Input Handling:** Use `THREE.Raycaster` to detect touches. * Normalize touch coordinates (`-1 to +1`) correctly regardless of canvas resizing. * **Feedback (Juice):** * **Haptic:** Trigger `navigator.vibrate(50)` on a successful find and `navigator.vibrate([100, 50, 100])` on a mistake. * **Visual Feedback:** The touched image plane should subtly scale down (`0.98`) and bounce back (`1.0`) to simulate a tactile surface. * **UI Touch Zones:** ensure all UI buttons (Hint, Pause) are at least 44x44 pixels. * **Emoji Interaction:** Add a small overlay menu with 4 Emoji buttons (Happy, Angry, Thinking, Sad). Clicking one floats that emoji up the screen (simulating the multiplayer social feature). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
