CUSTOM FONTS (OPTIONAL):

To add custom fonts to the diving game:

1. Download Roboto font files:
   - Roboto-Regular.ttf
   - Roboto-Bold.ttf

2. Place them in this directory (assets/fonts/)

3. Uncomment the fonts section in pubspec.yaml

4. Update the fontFamily in lib/main.dart to 'GameFont'

Font sources:
- Google Fonts: https://fonts.google.com/specimen/Roboto
- fonts.google.com (free download)

The game will work perfectly with system fonts, 
but custom fonts can enhance the visual experience.
