Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "One More Line". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist "Disco-Neon" aesthetic. The background should be a clean, slightly off-white or very light grey to make the colors pop. * **Player Character**: A simple, stylized cockpit or "shuttle" (represented by a white geometric shape, similar to the logo's 'D' shape or a sleek arrowhead). It must leave a persistent trail behind it. * **The Trail**: This is the most crucial visual element. It should be a multi-colored ribbon (pink, yellow, cyan stripes) that persists on the screen, creating abstract art as the player progresses. Use a `BufferGeometry` or `MeshLine` to efficiently render this growing trail without performance drops. * **Obstacles/Grapple Points**: Scatter circular nodes (representing grapple points) procedurally along the path. These should pulse slightly or have a glowing ring effect. * **Camera**: A top-down Orthographic camera that smoothly follows the player's upward vertical progression. The movement should feel fluid, not jerky. * **Performance**: Use simple geometric primitives (CircleGeometry, PlaneGeometry) to ensure 60FPS on mobile browsers. Avoid complex dynamic lighting; use baked colors or unlit materials for a vibrant, flat look. ### 2. Audio Requirements * **BGM**: A catchy, high-energy Nu-Disco or Electro-Funk loop. It should have a strong bassline and synth chords that match the "neon" aesthetic. * **SFX**: * **Grapple/Swing**: A "zip" or "latching" magnetic sound when the player connects to a node. * **Release**: A "whoosh" or release sound when letting go. * **Crash/Game Over**: A digital "crunch" or static glitch noise. * **Score Ticks**: A subtle click or blip for every meter traveled. ### 3. Gameplay Loop * **Core Mechanic**: The player's shuttle constantly moves forward (upwards). The player cannot steer directly. * **Grappling**: When the player touches and holds the screen, the shuttle shoots a "grapple beam" to the nearest circular node. The shuttle then begins to orbit that node in a perfect circle. * **Timing**: The player must release the hold at the exact right moment to launch the shuttle forward towards the next set of nodes. * *Too early/late release*: The shuttle flies off sideways into the "wall" (screen bounds) -> Game Over. * *Perfect release*: The shuttle shoots straight up the center. * **Collision**: Crashing into the side boundaries or slamming directly into the center of a node results in a Game Over. * **Scoring**: Score is based on distance traveled. * **Endless Mode**: The level is procedurally generated and infinite. ### 4. Mobile Controls & Interaction * **Control Scheme**: One-finger Interaction (Touch & Hold). * **Touch Start**: Activates the grapple hook to the nearest node. * **Touch End (Release)**: Detaches the grapple, flinging the player tangentially. * **Screen Orientation**: Portrait mode is mandatory for this vertical scrolling game. * **Haptic Feedback**: Trigger a light vibration (`navigator.vibrate(10)`) when the grapple successfully connects, and a heavy vibration on Game Over. * **UI Layout**: * A "Tap and Hold to Swing" tutorial overlay on the first run. * Current score displayed prominently at the top center in a modern sans-serif font. * A large, thumb-friendly "Restart" button that appears instantly upon death. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

One More Line is a highly addictive casual arcade game that challenges players to grow their line as long as possible through precise timing and skill. This minimalist one-button game combines simple controls with increasingly difficult gameplay, creating an experience that's easy to learn but incredibly hard to master.

The game's elegant design features a colorful line that players must skillfully navigate through various anchor points, creating mesmerizing patterns while avoiding deadly obstacles. With its sleek visual style and responsive controls, One More Line offers endless entertainment for players seeking a quick gaming session or extended play.

Core Features

Addictive One-Button Gameplay

The beauty of One More Line lies in its simplicity. Using just the space bar, players control when their line swings from anchor point to anchor point. This minimalist approach makes the game accessible to everyone while maintaining incredible depth and challenge.

Progressive Difficulty

As your line grows longer, the game becomes increasingly challenging. Navigate through tighter spaces, react faster to obstacles, and maintain your rhythm as the complexity builds. Each successful swing brings new challenges and requires split-second decision making.

Endless Arcade Action

With no levels or endings, One More Line provides unlimited replayability. Every game is a fresh attempt to beat your personal best and achieve that perfect run. The game's infinite nature means there's always room for improvement.

Stunning Visual Design

Featuring a clean, modern aesthetic with vibrant colors against a sleek black background, the game creates beautiful geometric patterns as you play. The visual feedback enhances the gameplay experience and creates satisfying moments with every successful swing.

Game Mechanics

The core mechanic revolves around timing your swings perfectly. Hold the space bar to swing your line around anchor points, but release at exactly the right moment to continue your journey. Hit the sides or obstacles, and your run ends immediately.

The challenge comes from reading the upcoming path, anticipating the perfect timing, and maintaining your rhythm as the line grows longer and the obstacles become more complex. Success requires patience, practice, and precise timing.

Winning Strategy

Success in One More Line requires developing a feel for the game's rhythm.
