Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Spooky-Cute Monster Merge**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Use a **"3D Sticker" aesthetic** similar to the reference image. Models should be low-poly but use **Toon Shading (MeshToonMaterial)** with vibrant colors. If possible, add a thick white outline effect to the 3D models (using the inverted hull method or similar shader technique) to mimic the 2D sticker look. * **Characters**: Create a hierarchy of monsters. * *Level 1*: A simple cute slime ghost. * *Level 2*: A one-eyed bat. * *High Level*: A **Unicorn wearing a suit and sunglasses** (as seen in the reference), featuring a pink punk-style mane. * **Environment**: An **Isometric perspective** camera setup. The game board is a grid (e.g., 5x5 tile board) floating in a mystical void. The background should be a **vibrant gradient purple** (matching the reference image) with subtle floating dust particles or bat silhouettes. * **Optimization**: Use `InstancedMesh` for grid tiles and lower-level monsters to ensure 60FPS on mobile devices. Texture resolution should be kept low (512x512 max) with baked lighting where possible. ### 2. Audio Requirements * **BGM**: A loop that sounds like "Whimsical Halloween"—a mix of pizzicato strings, a playful theremin, and a light hip-hop beat. It should be catchy, not scary. * **Sound Effects (SFX)**: * *Spawn*: A soft "pop" sound. * *Drag*: A "whoosh" or stretching rubber sound. * *Merge Success*: A satisfying, magical "ding" or "crunch" combined with a sparkle sound. * *Unlock New Zone*: A short fanfare trumpet burst. * *UI Click*: Wood block or bubble pop sounds. ### 3. Gameplay Loop * **Core Mechanic**: The board fills with lower-level monsters over time (or via a "Spawn" button). The player must drag a monster onto an identical monster to merge them into the next tier (e.g., 2x Level 1 = 1x Level 2). * **Progression**: Merging generates "Essence" (currency). Earning enough Essence clears "Fog" from the edges of the map, revealing new grid tiles (representing the Castle expansion mentioned in the description). * **Goal**: Unlock the highest-tier monster (The Cool Unicorn) to complete the "Castle" world and trigger a visual transition to the "Fairy World" (changing background colors from purple/dark to pastel pink/green). ### 4. Mobile Controls & Interaction * **Input System**: Use `THREE.Raycaster` mapped to touch events (`touchstart`, `touchmove`, `touchend`). * *Touch Start*: Select the monster, scale it up slightly (1.2x) to indicate selection, and play a lifting animation. * *Touch Move*: The monster follows the finger position directly (1:1 movement). **Crucial**: Prevent default browser scrolling (`e.preventDefault()`) on the canvas to ensure smooth dragging. * *Touch End*: Drop the monster. If dropped on a matching target -> Merge. If dropped on empty tile -> Move. If dropped invalidly -> Snap back to original position. * **Orientation**: **Portrait Mode** design. The grid should be centered vertically to be reachable by a thumb. * **UI/UX**: * Large, thumb-friendly buttons (min 44px) at the bottom for "Spawn Monster" or "Shop". * **Haptic Feedback**: Trigger `navigator.vibrate(20)` on a successful merge for tactile satisfaction. * Visual Feedback: When merging, spawn a particle explosion (confetti or stars) to reward the player. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
