Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Opposite Day**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a clean, minimalist aesthetic inspired by flat vector art but rendered in a 3D orthographic view (OrthographicCamera). Use high-contrast colors: bright white/light blue striped backgrounds, solid black platforms, and a vibrant blue square for the player character. * **Player Character:** A simple blue cube geometry with two black circular "eyes" on the front face to give it character. The cube should rotate slightly in the direction of movement to add dynamism. * **Level Design:** Build a 2D side-scrolling environment using 3D blocks. * **Platforms:** Solid black rectangular prisms. * **Hazards:** Red zones or spikes that reset the level on contact. * **"Instruction" Text:** Floating 3D text in the background (e.g., "GO RIGHT", "DONT JUMP") that serves as the core puzzle element. * **Performance:** Use `BoxGeometry` and `MeshBasicMaterial` primarily to keep draw calls low for mobile. Avoid expensive shadows; use baked-in ambient occlusion or simple localized shadow planes beneath the player. ### 2. Audio Requirements * **BGM:** A quirky, slightly off-beat chiptune or synth-pop track. It should sound playful but slightly "wrong" (e.g., occasional reversed notes or discordant harmonies) to fit the "Opposite" theme. * **SFX:** * **Jump:** A retro "boing" or digital ascending slide. * **Death/Reset:** A glitchy "record scratch" or a descending low-bit tone. * **Win/Level Clear:** A satisfying, crisp chime. * **UI Interaction:** Soft clicks for button presses. ### 3. Gameplay Loop * **Core Mechanic - The "Opposite" Logic:** The central hook is that the text instructions lie. * If the text says "GO RIGHT", the level exit is actually to the *left*. * If the text says "JUMP HERE", there is an invisible ceiling; the player must walk under. * If the text says "TOUCH THE RED", the red blocks are safe and the black ones are lava. * **Control Reversal (Level Specific):** In certain "hard mode" zones, the actual inputs should flip (pressing Right moves Left). * **Objective:** Reach the "Exit" flag/zone to progress to the next level. * **Failure:** Touching a hazard or falling off the map instantly resets the player to the start of the current level. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Landscape mode is mandatory for the side-scrolling perspective. * **Touch Controls:** Implement a transparent, intuitive on-screen overlay. * **Left Side:** Two large arrow buttons (Left/Right) for horizontal movement. * **Right Side:** A large circular "Jump" button. * **Top Corner:** A small "R" button for quick restart (crucial for a "difficult" puzzle game). * **Haptic Feedback:** Trigger a short, sharp vibration (using `navigator.vibrate`) when the player dies or completes a level. * **Visual Feedback:** When buttons are pressed, they should scale down slightly or change opacity to confirm input. The camera should smoothly follow the player with a slight dampening effect (Lerp) to prevent motion sickness on small screens. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
