Change the default fonts

@marcooooo: The font family option is not available in the free version of the theme. I suggest you to upgrade to pro. You can also check out the additional-features available in pro version of the theme.

Alternately you can also use additional CSS Code to change fonts.
Let me know what you would like to do.

@marcooooo: Go to => Appearance => Customize => Additional CSS and the following CSS Code.

To change font of text and menu bar

.menu, .entry-content, .entry-summary {
     font-family: Century Gothic, CenturyGothic, AppleGothic, sans-serif;
}

To use Shadows into light font first you will need to create a child theme. If you do not to how to create a chlild theme you can use Generate Child Theme plugin. Then download the Shadows into light font and paste the font files into your child theme folder in fonts folder. Also add the following CSS Code to style.css in your child theme folder.

@font-face {
    font-family: Shadows;
    src: url(fonts/ShadowsIntoLight.ttf);
}

Go to => Appearance => Customize => Additional CSS and add the following CSS Code.
To change font of post title

}
