My game is in English and I would like to change the language of the game.

The game is using the language that is set as default for your OS. To change the language, please set another language as default in your OS language settings:

• Go to Start  > Settings > Time & language > Region & language.
• Choose one of your languages and then select Options.
• Select Download from the Download language pack option. 
• Once the language pack is installed, select back.
• Choose one of your languages that reads Language pack installed and then select Set as default to make that language the Windows 10 display language.
• You may need to restart your system to apply the changes.
