Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Level Devil: The Troll Platformer**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist "2.5D" geometry. The world should be built using simple geometric shapes (BoxGeometry, PlaneGeometry) but rendered with flat, vibrant colors to mimic the game's retro pixel-art aesthetic. * **Palette**: Bright yellow background (`#FFD700` or similar), solid black for the player character and key dynamic obstacles, and dark red/brown for static hazards like spikes. * **Lighting**: Flat, ambient lighting to ensure high visibility. Use a directional light to cast hard, dramatic shadows (like in the screenshot) to give depth to the 2D plane. * **Player Model**: A simple black cube or a composite of small cubes to represent the "pixel hero." It needs a "squash and stretch" animation effect on jump and land to add juice. * **Performance Optimization**: Keep geometry low-poly. Use `InstancedMesh` for repetitive elements like spikes or floor tiles. Ensure the scene rendering loop is optimized for 60fps on mobile browsers. Use a fixed Orthographic Camera to simulate a 2D side-scrolling perspective while leveraging 3D depth for trap animations. ### 2. Audio Requirements * **BGM**: A quirky, slightly mischievous chiptune track. It should be catchy but repetitive, designed to be annoying in a funny way (looping short playful motifs). * **Sound Effects (SFX)**: * **Jump**: A retro 8-bit "up" sound. * **Death/Splatter**: A comical "crunch" or synthesized "womp-womp" noise when hitting spikes. * **Trap Trigger**: A sharp "shwing" or mechanical "click" when a hidden trap activates (e.g., a wall suddenly moving). * **Win/Door**: A triumphant, short fanfare when touching the exit door. ### 3. Gameplay Loop * **Objective**: Guide the black cube character from the starting point (left) to the exit door (right). * **The "Troll" Mechanic**: The core loop relies on subverting player expectations. * **Surprise Hazards**: Platforms that fall when stepped on, spikes that pop out of safe-looking ground, or invisible walls that appear mid-jump. * **Dynamic Level**: As the player progresses, the level geometry changes (e.g., the door moves away just as you reach it). * **Victory Condition**: Reaching the exit door collision box triggers the "Level Complete" state. * **Failure Condition**: Touching any red object (spikes, sawblades) or falling off the map triggers immediate death. * **Instant Respawn**: Upon death, the player must *instantly* reset to the spawn point with zero loading time to maintain the "rage game" momentum. ### 4. Mobile Controls & Interaction * **Orientation**: **Landscape Mode** is mandatory for this platformer layout. * **Touch Controls (Virtual Gamepad)**: * **Left Side**: Two large, invisible touch zones or semi-transparent arrow icons for Left/Right movement. * **Right Side**: A large circular button area for Jump. * **Responsiveness**: Controls must be ultra-responsive with zero input lag. Support multi-touch so the player can run and jump simultaneously. * **UI Feedback**: * Buttons should scale down slightly when pressed. * Trigger Haptic Feedback (using `navigator.vibrate` if available) on death and when landing a jump. * **Menus**: A simple "Pause" icon in the top corner (min 44x44px hit area) that opens a menu with "Resume" and "Restart Level." ### 5. Implementation Notes * **Physics**: Use a simple custom physics implementation (AABB collision detection) rather than a heavy engine like Cannon.js, as the movement needs to feel arcade-snappy, not realistic. * **Level Generation**: Define level data in a simple JSON array (e.g., `[ { type: 'platform', x: 0, y: 0 }, { type: 'trap_spike', x: 5, y: 0 } ]`) to allow for easy creation of multiple "troll" stages. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
