Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Fish Drop - Ocean Merge**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D or 3D Low-poly style with a vibrant, cartoon aesthetic similar to "Suika Game" (Watermelon Game). The models should be simple geometric shapes (mostly spheres) wrapped with cute, expressive 2D textures or low-poly meshes representing different sea creatures. * **Fish Hierarchy (Small to Large):** Create a tiered system of at least 8 distinct physics objects (spheres): 1. Clownfish (Tiny, Orange) 2. Blue Tang (Small, Blue) 3. Shrimp-Cat Hybrid (Medium, Red/Striped - wacky design based on reference) 4. Squid (Medium, Purple) 5. Tiki/Wood Totem Fish (Large, Brown - wacky design) 6. Shark (Very Large, Grey) 7. Plane-Fish Hybrid (Huge, Grey/Green - wacky design) 8. **The Golden Pufferfish** (The Goal, Massive, Spiky, Glowing). * **Container:** A translucent, U-shaped glass aquarium or "cup" container. It should be open at the top. Use `MeshPhysicalMaterial` for a glass-like refraction effect but keep it performant. * **Background:** A simple gradient blue ocean backdrop. Add subtle rising bubbles using a basic particle system to give the feeling of being underwater without consuming too much GPU. * **Lighting:** Bright, ambient light combined with a directional light from the top-left to cast soft shadows inside the container. * **Optimization:** Use instanced meshes if possible for the fish to handle many objects on screen. Limit texture resolution to 512x512. ### 2. Audio Requirements * **BGM:** A looping, cheerful, tropical-style track using steel drums, ukulele, and light percussion. It should be relaxing but catchy. * **SFX:** * *Spawn/Ready:* A light "pop" sound when a new fish appears at the top. * *Drop:* A "whoosh" or water splash sound. * *Collision:* Soft, rubbery thuds when fish hit each other or the walls. * *Merge:* A satisfying, magical "sparkle" or high-pitched "bloop" sound when two identical fish combine. * *Game Over:* A sad trombone or glass cracking sound. ### 3. Gameplay Loop * **Core Mechanic:** The classic "Suika" (Watermelon) physics merge mechanic. A "next fish" spawns at the top of the container. The player positions it horizontally and drops it. * **Physics:** Use a physics engine (like Cannon.js or Amo.js integrated with Three.js). The fish must have bouncy, rolling physics. Gravity should be standard. * **Merging:** When two objects of the *same tier* collide, they must immediately despawn and be replaced by one single object of the *next tier up* at the midpoint of the collision. * **Game Over:** If the fish stack up and cross a "Danger Line" at the top of the container for more than 3 seconds, the game ends. * **Score:** Display a score at the top. Merging small fish gives small points; merging large fish gives massive points. ### 4. Mobile Controls & Interaction * **Orientation:** Portrait mode (Vertical) is mandatory for this container-filling gameplay. * **Touch Input:** * *Drag:* The player touches anywhere on the screen and drags left/right. The "current fish" at the top strictly follows the finger's X-axis position but stays at a fixed Y-axis height (above the container). * *Release:* Lifting the finger triggers the physics drop. * **Cooldown:** Add a short cooldown (0.5s) between drops to prevent spamming glitches. * **UI/UX:** * Show a "Next Up" preview in the top right corner (UI) so the player knows what fish is coming after the current one. * Add a "Restart" button in a safe corner (top left), at least 44x44px. * **Haptic Feedback:** If the device supports it (via `navigator.vibrate`), trigger a tiny vibration (50ms) on a successful merge. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About Fish Drop

Fish Drop is a captivating merge puzzle game that combines the satisfaction of physics-based gameplay with the addictive nature of merging mechanics. Your mission is simple yet engaging: drop fish into a container and merge identical species to create progressively larger fish, with the ultimate goal of growing the biggest pufferfish possible.

The game features colorful, cartoon-style fish characters that bring personality and charm to every merge. From small tropical fish to massive pufferfish, each creature has its own unique design and personality that makes the merging process visually rewarding.

Core Features

Physics-Based Merging System

Fish Drop utilizes realistic physics mechanics that make every drop feel natural and satisfying. When you release a fish, it falls naturally under gravity, bouncing and settling into position before merging with identical fish upon contact.

Progressive Fish Evolution

Start with small, basic fish and watch them evolve into larger, more impressive species through strategic merging. The progression system keeps you engaged as you work toward creating the ultimate pufferfish.

Intuitive Controls

The game features simple drag-and-drop controls that work seamlessly across all devices. Whether you're using a mouse on desktop or touching your mobile screen, the controls feel responsive and natural.

Free-to-Play Experience

Enjoy the complete Fish Drop experience without any cost. The game is entirely free to play with no hidden fees, subscriptions, or pay-to-win mechanics.

Cross-Platform Compatibility

Play on any device - desktop computers, laptops, smartphones, or tablets. The game runs smoothly in web browsers without requiring downloads or installations.

Game Mechanics

Strategic Placement

Success in Fish Drop requires more than just dropping fish randomly. You need to think strategically about placement to create chain reactions and maximize merging opportunities.

Container Management

Keep an eye on your container space! If fish pile up too high, your game ends. Balance aggressive merging with careful space management to achieve high scores.

Chain Reactions

When fish merge, they can trigger additional merges in a satisfying chain reaction. Master the art of setting up these cascading combinations for maximum points.

Operation Guide
