Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Return Portal**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D Minimalist Puzzle Platformer. Use an **Orthographic Camera** to maintain the precision of the original 2D logic but render assets as 3D geometry. * **Color Palette**: Strictly follow the screenshot's high-contrast scheme: * **Background**: A dark purple/indigo checkerboard pattern (approx. `#232338` and `#2A2A40`) to aid grid alignment. * **Player**: A simple, vibrant lime-green Cube (`#8CEA56`) with slightly rounded bevels (using `BoxGeometry` or `RoundedBoxGeometry`) and two simple black spheres for eyes. * **Terrain**: Flat geometric blocks with a yellow/orange top trim (`#FACC70`) and dark purple body (`#3E2754`). * **The Portal/Teleporter**: A pulsating, translucent cyan wireframe cube or a glowing particle ring (`#33AAFF`) that rotates when placed. * **Performance Optimization**: Use `InstancedMesh` for level blocks to reduce draw calls. Use simple Lambert or Phong materials; avoid expensive real-time shadows. Bake basic ambient occlusion if possible, or use flat shading for a clean aesthetic. ### 2. Audio Requirements * **BGM**: A "Think-style" chiptune or lo-fi electronic track. It should be calm, repetitive, and conducive to puzzle solving, not fast-paced. * **Sound Effects (SFX)**: * **Jump**: A short, retro rising sine wave "bloop". * **Place Portal**: A mechanical "click" or "set" sound. * **Teleport**: A digital "woosh" or "zap" sound with a slight echo. * **Key Collection**: A high-pitched, rewarding 8-bit chime. * **Death/Restart**: A low-pitch disintegration noise. ### 3. Gameplay Loop * **Objective**: The player must navigate a grid-based level to collect a **Key** (floating yellow token) and reach the **Gate/Door** to advance to the next level. * **Core Mechanic - The Teleporter**: * **Action A (Place)**: If the player holds the teleporter, pressing the Action button drops a "Ghost Marker" at the player's current coordinate. The player can then move away from it. * **Action B (Return)**: If a Ghost Marker exists, pressing the Action button instantly teleports the player back to the marker's coordinates, and the marker is retrieved (cooldown resets). * **Puzzle Logic**: Players must use this to traverse impossible gaps (e.g., drop teleporter, jump into a pit to grab a key, teleport back out before hitting spikes). * **Hazards**: Spikes, bottomless pits, and moving laser walls. Touching these triggers an instant level restart. ### 4. Mobile Controls & Interaction * **Screen Orientation**: **Landscape Mode** is mandatory to see the level layout ahead. * **Touch Controls (UI Overlay)**: * **Left/Right**: Two distinct arrows on the bottom-left of the screen (hitbox size min 60x60px). * **Jump**: A round button on the bottom-right. * **Action (Teleport)**: A distinct, larger button next to the Jump button (labeled with a Portal icon or "X"). This button must support multi-touch (can be pressed while holding Left/Right). * **Restart**: A small "R" or refresh icon in the top-right corner. * **Feedback**: * **Haptic**: Trigger a light vibration (`navigator.vibrate(50)`) when the player teleports or collects a key. * **Visual**: When the Action button is pressed to teleport, generate a brief trail renderer effect or particle burst at both the origin and destination. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
