| # Brick Breaker Game | ||
|
|
||
| This is a simple Brick Breaker game built using HTML, CSS, and JavaScript. The game involves a paddle that the player moves left and right to bounce a ball against bricks, breaking them. | ||
|
|
||
| ## How to Play | ||
|
|
||
| - Use the left and right arrow keys to move the paddle. | ||
| - The objective is to break all the bricks without letting the ball fall off the screen. | ||
| - You have 3 lives. If you lose all lives, the game is over. | ||
|
|
||
| ## Files | ||
|
|
||
| - `index.html`: The main HTML file that sets up the game canvas. | ||
| - `style.css`: The CSS file for styling the game canvas and background. | ||
| - `script.js`: The JavaScript file containing the game logic and rendering. | ||
|
|
||
| ## How to Run | ||
|
|
||
| 1. Clone or download this repository. | ||
| 2. Open `index.html` in your web browser. | ||
|
|
||
| ## Future Enhancements | ||
|
|
||
| - Add more levels with increasing difficulty. | ||
| - Implement power-ups like larger paddles, extra balls, etc. | ||
| - Add sound effects and background music. | ||
