MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Untangle (Cosmic Web)". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Minimalist "Deep Space" aesthetic. The background should be a dark, high-contrast gradient (deep blue to black) with a slowly rotating starfield or subtle nebula particle system to create depth without distraction. * **Nodes (Vertices):** Represented as glowing spheres (neon white or cyan). Use `THREE.SphereGeometry` with a `MeshBasicMaterial` combined with a Bloom effect (UnrealBloomPass) to make them look like stars. * **Lines (Edges):** Represented as laser-like connections. * **State A (Intersecting/Tangled):** Color should be Red or Dim White to indicate conflict. * **State B (Safe/Untangled):** Color should turn Bright Green or Cyan instantly when the line no longer crosses any other line. * **Material:** Use thick lines (e.g., `MeshLine` or distinct `THREE.LineSegments` with proper opacity) to ensure visibility on small mobile screens. * **Performance:** Use `InstancedMesh` for nodes if the count exceeds 50 (though unlikely for this game type). Ensure the Bloom pass is optimized for mobile GPUs (lower resolution buffer). ### 2. Audio Requirements * **BGM:** An ambient, ethereal, and "Zen" electronic track. It should be loopable and non-intrusive to aid concentration (think Brian Eno style). * **Sound Effects (SFX):** * **Touch/Grab:** A soft "pop" or digital hum when the player touches a node. * **Drag:** A subtle frequency shift or low hum while moving a node. * **Untangle Event:** A satisfying high-pitched "ping" or glass resonance sound when a line changes from Red (crossed) to Green (safe). * **Level Win:** A harmonious chord progression accompanied by a visual pulse. ### 3. Gameplay Loop * **Core Mechanic:** The game generates a **Planar Graph** where vertices (nodes) are connected by edges (lines). At the start of the level, the vertices are randomized such that multiple lines intersect. * **Interaction:** The player drags vertices to new positions on the 2D plane (X, Y axis only). * **Logic/Validation:** * Implement a strictly 2D line-segment intersection algorithm. * **Real-time check:** Every frame (or on mouse move), check every line against every other line. * If Line A intersects Line B, both glow Red. If not, they glow Green. * **Win Condition:** When **zero** intersections are detected, the level is complete. Wait 1 second, play the victory animation, and generate a new graph with increased complexity (N+1 nodes). ### 4. Mobile Controls & Interaction * **Touch Input:** Implement a `Raycaster` mapped to standard Touch Events (`touchstart`, `touchmove`, `touchend`). * **Hit Testing:** The invisible hit-box for the nodes must be 20-30% larger than the visual sphere to accommodate "fat finger" errors on mobile screens. * **Drag Behavior:** * Movement should be 1:1 with the finger but include slight smoothing (Lerp) for a premium feel. * Prevent the canvas from scrolling/zooming by setting CSS `touch-action: none`. * **Screen Orientation:** Portrait mode preferred. The camera should be an Orthographic Camera to ensure the puzzle remains a flat 2D plane without perspective distortion, keeping lines clearly legible. * **Feedback:** * **Haptics:** Trigger `navigator.vibrate(10)` when a line successfully untangles. * **Visuals:** When a node is held, scale it up by 1.2x to show selection. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Untangle is a brilliantly simple yet increasingly challenging puzzle game that has captivated millions of players worldwide. With an impressive 3.9/5 rating, this free online brain teaser offers the perfect blend of relaxation and mental stimulation. The concept is elegantly straightforward: untangle a web of interconnected lines by strategically moving nodes until no lines cross each other.

What makes Untangle truly special is its progressive difficulty system. Each level you complete presents a larger, more complex web of tangled lines, ensuring that the challenge grows with your skills. This makes it an ideal game for both casual puzzle enthusiasts and serious brain training devotees.

Core Features

Intuitive Gameplay Mechanics

The beauty of Untangle lies in its simplicity. Using only your mouse, you drag nodes (connection points) around the screen to reposition the web of lines. The goal is elegantly simple: arrange the nodes so that none of the connecting lines overlap or cross each other.

Progressive Difficulty System

Each successfully completed level unlocks a more complex puzzle with additional nodes and connections. This gradual increase in difficulty ensures that players are constantly challenged without becoming overwhelmed, making it perfect for both beginners and puzzle veterans.

Brain Training Benefits

Untangle isn't just entertainment – it's a powerful cognitive exercise that: - Enhances spatial reasoning abilities - Improves problem-solving skills - Develops patience and systematic thinking - Strengthens visual-spatial intelligence - Provides stress-relieving mental focus

Accessibility and Convenience

  • Completely Free : No hidden costs or premium features
  • Browser-Based : Play instantly without downloads
  • All Ages Content : Perfect for family-friendly gaming
  • Cross-Platform : Works on desktop, tablet, and mobile devices
  • No Time Pressure : Solve puzzles at your own pace

Game Mechanics

Understanding the Puzzle Structure

Each Untangle puzzle consists of a network of nodes connected by straight lines. These nodes can be freely moved around the playing area, and as you drag them, the connecting lines move with them. Your task is to find the perfect arrangement where no two lines intersect.

Strategic Approaches

Successful players often develop systematic approaches: - Start by identifying the most tangled areas - Work on separating major clusters of overlapping lines - Use the edges of the play area strategically - Think several moves ahead before making changes - Sometimes moving a node away from the target position temporarily helps untangle other areas

Operation Guide

Basic Controls

  • Mouse Click and Drag : Select any node and drag it to a new position
  • Visual Feedback : Lines turn different colors to indicate overlaps
  • Level Progression : Complete a puzzle to automatically advance to the next level
  • Reset Option : Most versions allow you to restart a level if you get stuck

Tips for Success

  1. Take Your Time : There's no time limit, so think through your moves
  2. Work Systematically : Focus on untangling one section at a time
  3. Use Space Wisely : Spread nodes out to give lines room to avoid crossing
  4. Experiment Freely : Don't be afraid to try different arrangements
  5. Think in 3D : Sometimes imagining the puzzle in three dimensions helps find solutions
