Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Aliens Attack". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Use a **Low-Poly, Toon-Shaded (Cel Shaded)** aesthetic to match the "Cute" and "Cartoon" tags. Colors should be vibrant and highly saturated (Neon Green aliens, Bright Orange explosions, Deep Blue sky). * **Player Character:** A stylized, blocky "Hero" character (resembling a soldier or a tough grandma like the reference image) positioned at the bottom center of the screen. The character should hold a weapon. * **Enemies:** Create 3 variations of "Alien Blobs" using deformed sphere geometries (e.g., Blue, Green, Purple). They should bob up and down slightly while moving. * **Environment:** A vertical scrolling background. A simple ground plane (grass or city street) with a parallax scrolling skybox containing stylized clouds or stars to give a sense of speed. * **Effects:** Use simple particle systems (instanced geometry) for explosions (orange cubes expanding and fading) and muzzle flashes. * **Optimization:** Use `THREE.InstancedMesh` for aliens and bullets to ensure 60FPS on mobile devices. ### 2. Audio Requirements * **BGM:** A fast-paced, energetic **8-bit / Chiptune style** track that loops. It should sound heroic and urgent. * **Sound Effects (SFX):** * **Shooting:** A high-pitched "Pew-Pew" retro laser sound. * **Explosion:** A crunchy, distorted noise when an alien dies. * **Game Over:** A descending "sad trombone" or power-down sound. * **UI:** A crisp "click" sound for starting the game. ### 3. Gameplay Loop * **Core Mechanism:** A vertical shooter (shmup). The player is confined to the bottom of the screen (ground level) and can only move Left and Right (X-axis). * **Shooting:** The player **auto-fires** projectiles upwards constantly (every 0.2s). This simplifies mobile input. * **Enemy Behavior:** Aliens spawn at the top of the screen in waves and descend slowly. Some aliens should move in a zig-zag pattern, others straight down. * **Scoring:** +100 points for every alien destroyed. Display the score prominently at the top left. * **Lose Condition:** If an alien collides with the player OR reaches the bottom of the screen, the game ends. Show a "Game Over" overlay with a "Retry" button. ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Portrait Mode** (Vertical) is required for one-handed play. * **Control Scheme:** Implement a **"Touch & Drag"** system. * The player can touch anywhere on the bottom half of the screen. * Dragging the finger Left/Right moves the character horizontally. * Movement should be 1:1 with finger movement for responsive control (relative positioning). * **UI Elements:** * Start/Restart Button: Large, centered, at least 60x60px clickable area. * Score Text: Large, bold font visible on small screens. * **Feedback:** Trigger `window.navigator.vibrate(50)` (haptic feedback) whenever the player destroys an enemy or gets hit. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
