Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**One Chance - Mobile Remake**". 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. Use `THREE.PlaneGeometry` with pixel-art textures for characters and props (billboard style), set against a layered 3D background to create a parallax effect. * **Character Model**: The protagonist (John Pilgrim) should be a 2D sprite mapped on a plane. He needs animation states for: Idle (standing still), Walk (2-frame bobbing animation), and Interact (reaching out). * **Dynamic Atmosphere**: The lighting and sky color must evolve based on the "Day" variable: * **Day 1**: Bright blue sky, vibrant green plants (high saturation). * **Day 3**: Orange/Hazy sky, dimmer lighting (fog). * **Day 6**: Dark Grey/Red sky, dead vegetation sprites, sparse particle effects like ash falling. * **Performance**: Use a single texture atlas for all sprites to reduce draw calls. Use `THREE.MeshBasicMaterial` (unlit) to preserve the retro flash game look and ensure high FPS on mobile devices. ### 2. Audio Requirements * **BGM Progression**: Implement a day-based music state machine: * *Early Game*: Hopeful, simple chiptune or light piano. * *Mid Game*: A discordant, slow drone sound. * *Late Game*: Silence or a very slow, melancholic minor-key piano melody. * **SFX**: * **Footsteps**: Retro "tap" sounds synced with the walking animation. * **UI**: A "typewriter" sound effect when text/dialogue appears letter-by-letter. * **Interaction**: A sharp 8-bit "blip" when selecting a choice. ### 3. Gameplay Loop * **The 6-Day Cycle**: The game logic is driven by a `currentDay` variable (1 to 6). * **Daily Routine**: 1. **Morning**: Display a "Newspaper Headline" UI overlay (e.g., "CURE DEADLY") that requires a tap to dismiss. 2. **Traversal**: Player walks from left (Home) to right (Car/Lab). 3. **Choice Node**: Trigger a modal dialog when interacting with key objects (Car, Lab Door, Family). Choices: "Work on Cure" vs "Stay with Family". * **Narrative Branching**: Track a hidden variable `cureProgress` and `familyBond`. * If `cureProgress` < threshold by Day 6: "Bad Ending" (Everyone dies). * If `cureProgress` > threshold: "Good Ending" (Cure found, but John might die). * **The "One Chance" Mechanic**: On Game Over, set a flag in `localStorage`. If the user reloads, show a black screen with text: "You only get one chance." (Include a hidden developer reset button for testing purposes). ### 4. Mobile Controls & Interaction * **Orientation**: Landscape Mode (force logic to scale viewport width). * **Movement**: A virtual "Slider" or distinct "Left/Right" arrows on the bottom-left of the screen. High contrast (white arrows on semi-transparent black). * **Interaction**: A large, context-sensitive "Action Button" (e.g., "TALK", "WORK", "DRIVE") on the bottom-right. It only appears when the player is within the trigger zone of an interactable object (use `raycaster` or distance checks). * **Feedback**: * **Visual**: The interact button pulses when active. * **Haptic**: Trigger `navigator.vibrate(50)` when a major narrative choice is made. * **Text Readability**: Dialogue boxes must appear at the top center of the screen with a large, pixel-style font (minimum 16px equivalent size) to ensure readability on small screens. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
