speedy-ben-skins/Skins/main nm skin/font

This folder contains fonts that the skin uses. You probably shouldn't touch
anything here unless you know what you're doing.

If you want to customize the font used for combo, score or hitcircles, try
editing the [Fonts] section in the skin.ini file.

For example, you can change ComboPrefix to "font/regular" to use thinner
combo numbers instead.
