Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "EvoWorld.io / FlyOrDie". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller aesthetic using an **Orthographic Camera**. Use a vibrant, "Cartoon/Flash-game" art style. The world should be flat, but composed of 3D planes or low-poly meshes to allow for smooth scaling and rotations. * **Color Palette:** High saturation. Sky blue background (`#4CC9F0`), bright green ground (`#70E000`), and brown dirt (`#8D5524`). * **Core Models:** * **Player:** Start as a simple **Fly** (black body, large white eyes, translucent wings). Use simple geometric shapes (Spheres/Cylinders) grouped together. * **Food Items:** Poop (Brown piles), Rotten Fruit, Dead Fish (depending on evolution stage). * **Environment:** Trees and Rocks as background sprites (Billboards) that do not interact with physics but provide parallax depth. * **Mobile Optimization:** Use `BoxGeometry` or `PlaneGeometry` for most elements to keep polygon count low. Implement object pooling for food items and enemy projectiles to prevent garbage collection stutters on mobile browsers. ### 2. Audio Requirements * **BGM:** A lighthearted, quirky, and looping track featuring pizzicato strings and woodwinds to emphasize the "sneaky survival" aspect. * **Sound Effects (SFX):** * **Movement:** A subtle, continuous high-pitched buzzing sound that changes pitch based on movement speed. * **Eating:** A comical "Slurp" or "Chomp" sound with immediate feedback. * **Evolution:** A magical, ascending chime or fanfare when the player transforms. * **Damage/Death:** A cartoonish "Splat" sound. * **UI:** Soft "Pop" sounds for button presses. ### 3. Gameplay Loop * **Evolution Mechanic:** The player starts as a "Fly". A UI bar at the top displays the specific diet (e.g., "Eat Poop"). * **XP System:** Every time the player collides with the correct food item, an XP bar fills up. Once full, the player model scales up, a particle effect explodes, and the player evolves into the next creature (Fly -> Butterfly -> Mosquito). The diet requirements must change upon evolution. * **Survival:** * **Predators:** AI Bots (Red outlined sprites) roam the map. If the player touches a predator (a higher-tier animal), it is Game Over. * **Resources:** If the player flies too high (into space) or goes underwater without being an aquatic creature, an "Oxygen/Air" bar depletes. * **Win/Loss:** * **Loss:** Eaten by predator or run out of oxygen. * **Win:** Reach the final evolution stage (e.g., Grim Reaper). ### 4. Mobile Controls & Interaction * **Primary Control (Virtual Joystick):** Implement a dynamic Virtual Joystick on the **Left** side of the screen. * Movement is free-flight (Omni-directional: Up, Down, Left, Right). * The character mesh should rotate to face the input direction (smooth lerp rotation). * **Action Button:** A large, circular button on the **Right** side of the screen for "Special Ability" (e.g., a short speed boost or 'Split' to escape). * **Camera Behavior:** The camera must smoothly follow the player (Soft Follow) with a slight offset, ensuring the player can see what is ahead of them. * **UI & UX:** * **Orientation:** Landscape Mode locked. * **Hitboxes:** Make food hitboxes 20% larger than their visual models to make gathering easier on small touch screens. * **Visual Feedback:** When eating, spawn floating "+XP" text and small particle crumbs. Screen shake slightly upon taking damage. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
