Python Puzzle Game

This code implements a simple puzzle game using the Pygame library. It loads a background image and puzzle piece images, creates a 3x3 grid of puzzle pieces, and allows the player to click and drag pieces to swap them. The game checks if the puzzle is solved after each move, and displays a congratulatory message if the puzzle is solved.

Here's a brief summary of the code:

• The Pygame library is imported and initialized.
• The game window is set up with a width of 483 pixels and a height of 480 pixels, and a caption of "Make Abdur - Puzzle Game".
• The background music and sound effects are loaded from sound files.
• The puzzle piece images are loaded from files and stored in a list called pieces.
• The game loop starts, which repeatedly draws the background image and puzzle pieces on the screen and waits for user input.
• User input is handled using Pygame's event handling system. Specifically, the game listens for QUIT, MOUSEBUTTONDOWN, MOUSEBUTTONUP, and MOUSEMOTION events.
• When the player clicks on a puzzle piece, the game stores the selected piece and its position.
• When the player drags the selected piece, the game swaps the selected piece with the piece under the mouse cursor and plays a sound effect.
• After each move, the game checks if the puzzle is solved by comparing the pixel arrays of the puzzle pieces to the pixel arrays of the original arrangement of the pieces.
• If the puzzle is solved, the game stops the background music and displays a congratulatory message on the screen. It also plays a winning sound and waits for a delay before closing the game window.
