Add “Mute/Unmute Background Music” Button

Currently, the game plays background music automatically, but there’s no option for the user to mute or unmute it. Adding a toggle button for background music will improve the user experience, especially for players who want to focus without music.

Skills Required:

HTML

CSS

JavaScript (ES6+)

Acceptance Criteria:

Add a Mute/Unmute button on the game UI (e.g., near the score or pause button).

Clicking the button toggles background music on/off.

The button’s label or icon should update accordingly (e.g., 🎵 / 🔇).

Works for all themes (Default, Neon Retro, Dark, Ocean Blue).

Works on desktop and mobile screens.
