[Feature Request]: Create Main Menu for Dreamyard

[Captain-T2004]

We need to implement the main menu for our Dreamyard game in Unity. The main menu should have the following buttons:

• New Game: Starts a new game from the beginning.
• Select Level: Opens a menu to select and start from a specific level.
• Instructions: Displays the game instructions and controls.
• Exit Game: Closes the game application.

Requirements:

1. New Game Button:

   • On clicking, it should start a new game from the first level.
   • Ensure it resets any previous game progress.

2. Select Level Button:

   • Opens a new menu where players can select and start from any level.

3. Instructions Button:

   • Displays a screen with instructions on how to play the game, including controls and game objectives.
   • Ensure the instructions are clear and easy to understand.

4. Exit Game Button:

   • Closes the game application.
   • Ensure it works correctly on all supported platforms.

Additional Notes:

• The main menu should be visually appealing and consistent with the game's overall art style.
• Ensure all buttons have appropriate hover and click effects to enhance user experience.
• The main menu should be accessible and intuitive for players of all ages.

Tasks:

• Design the main menu layout.
• Implement the New Game button functionality.
• Implement the Select Level button and its submenu.
• Implement the Instructions button and the instruction screen.
• Implement the Exit Game button functionality.
• Add hover and click effects to the buttons.
