In order to optimize the graphic creations of your games and to follow your graphic charter, you have the possibility of downloading your own font.
For this, it is necessary that your fonts are in the WOFF format or WOFF2 (lighter format) and that the file is not bigger than 10MB.
You can add your custom fonts in the text editor:
Go to the "Text Customization" screen
Click on "Add font"
Upload the font of your choice in WOFF format and activate it with the toggle
Select the font in the text editor
