    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {

How It Works

1. CardLayout is used to switch between the menu and game panels.
2. ScrollingTextPanel uses a javax.swing.Timer to animate "java" moving from right to left.
3. Buttons:
   • Level 1 → switches to the scrolling text panel.
   • Close → exits the program.
   • Level 3 → shows a placeholder panel.
4. Animation runs smoothly at ~33 FPS (30ms delay).

Running in NetBeans

1. Create a Java Application project.
2. Replace the default Main.java with the above code.
3. Press Run ▶️.

If you want, I can add a "Back to Menu" button inside the Level 1 and Level 3 panels so you can return without restarting the app.
Do you want me to add that?
