Please use Three.js to generate a **mobile-first game** with the theme "**Circle Ball**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Camera Setup**: Use an `OrthographicCamera` to replicate the flat, minimalist 2D aesthetic seen in the screenshot. The view should be fixed, centered on the game arena. * **Visual Style**: Minimalist Flat Design (High-contrast pastel colors). * **Background**: A solid cool color (e.g., Muted Teal/Cyan `#81C5D7`). * **The Arena**: A large central circle (`CircleGeometry`), lighter than the background (e.g., Pale Cyan `#CCEBF3`). * **The Player (Paddle)**: A curved arc segment created using `RingGeometry` (with specific `thetaStart` and `thetaLength`), colored dark grey or black (`#333333`). It moves along the circumference of the Arena. * **The Ball**: A simple small circle (`CircleGeometry`) or sphere, dark grey (`#333333`). * **VFX (Visual Effects)**: * **Trail Effect**: Implement a simple trail renderer or a particle wake behind the ball to indicate speed and direction (as seen in the screenshot). * **Impact Feedback**: A subtle "scale pulse" animation on the Paddle when the ball hits it. * **Dynamic Arena**: The Arena circle should smoothly interpolate its scale (grow/shrink) randomly during gameplay to increase difficulty. ### 2. Audio Requirements * **BGM**: A rhythmic, minimalist "Clockwork/Tick-Tock" style ambient track that slightly increases in tempo as the game speed increases. * **SFX**: * **Bounce**: A crisp "Woodblock" or "Ping Pong" tap sound when the ball hits the paddle. * **Score**: A subtle chime every 10 points. * **Game Over**: A low-pitch "Buzzer" or "Glass crack" sound when the ball leaves the circle. * **UI Click**: Standard soft click sounds for the restart button. ### 3. Gameplay Loop * **Core Mechanism**: Radial Pong. The ball spawns in the center and shoots outward at a random angle. The player controls a paddle rotating around the circle to block the ball. * **Physics & Logic**: * The ball travels in straight lines. * **Collision**: Detect if the ball's distance from the center equals the Arena radius. * **Bounce Logic**: If the ball hits the radius AND is within the angle arc of the Paddle -> Reflect the ball back towards the center (invert velocity vector relative to the normal). * **Fail State**: If the ball hits the radius AND misses the Paddle -> The ball flies out, Game Over. * **Progression**: * **Speed**: Every successful bounce increases the ball's velocity by 5%. * **Arena Mutation**: Randomly change the radius of the Arena circle (smooth lerp) every 5-10 seconds to mess with the player's distance judgment. * **Scoring**: +1 point for every successful bounce. Display the score in the center of the circle (behind the ball layer). ### 4. Mobile Controls & Interaction * **Control Scheme**: **"Follow Finger" / Absolute Rotation**. * Do not use virtual buttons. * Calculate the angle (`Math.atan2`) between the center of the screen `(0,0)` and the user's touch/mouse position. * The Paddle should rotate to match this angle immediately (or with very fast `lerp` for smoothness). * **Orientation**: Force **Portrait Mode** layout logic (the circle fits the width of the phone). * **UI & UX**: * **Start/Restart**: Tap anywhere on the screen to start. * **Haptic Feedback**: Trigger `navigator.vibrate(20)` on a successful paddle hit. Trigger a longer vibration on Game Over. * Ensure the touch event listener prevents default scrolling behavior (`e.preventDefault()`). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About Circle Ball

Circle Ball is a fast-paced physics clicker game that combines elements of ping pong with circular gameplay mechanics. Rated 3.7/5 by players, this engaging browser game challenges your reflexes, timing, and ability to judge distances as you control a paddle around a magical circle to prevent a bouncing ball from escaping.

The game starts simple but quickly becomes an intense test of concentration and quick thinking. As you progress, the ball moves faster, the circle changes size, and your reflexes are pushed to their limits in this addictive clicker experience.

Core Features

Unique Circular Gameplay

Unlike traditional paddle games, Circle Ball features a 360-degree playing field where you control a paddle that moves around the perimeter of a circle. This creates a completely new type of ball-bouncing challenge that requires spatial awareness and quick decision-making.

Progressive Difficulty System

The game features an intelligent difficulty scaling system : - Ball speed increases gradually as you play longer - Circle size changes dynamically, affecting ball trajectory - No power-ups or shortcuts - pure skill-based progression - Each session becomes more challenging than the last

Instant Browser Gaming

  • Completely free to play with no hidden costs
  • No downloads required - play instantly in any modern browser
  • Cross-platform compatibility - works on desktop, mobile, and tablet
  • HTML5 technology ensures smooth performance across all devices

Competitive Elements

  • High score leaderboards to compete with other players
  • Personal best tracking to monitor your improvement
  • Endless gameplay with no level caps or restrictions

Game Mechanics

Circle Ball operates on realistic physics principles that make each bounce unpredictable yet logical. The ball follows natural trajectories, bouncing off the paddle and circle walls with momentum that changes based on impact angle and force.

The dynamic circle system is a key feature - the playing area can shrink or expand during gameplay, dramatically affecting ball behavior and requiring instant adaptation of your strategy.

Operation Guide

Basic Controls

  • Mouse : Click anywhere on the game area to position your paddle
  • Touch : Tap the screen to move the paddle (mobile devices)
  • Objective : Keep the ball inside the circle by blocking its escape routes
  • Timing : Click at the right moment to position your paddle effectively

Winning Strategy Tips

  1. Anticipate ball movement by watching its trajectory and speed
  2. Position your paddle ahead of where the ball will be, not where it is
  3. Stay calm as the game speeds up - panic leads to mistakes
  4. Practice short sessions to build muscle memory and improve reflexes
  5. Watch for circle size changes and adjust your strategy accordingly
