There´re no subtitles, only in the first minute lmao.

Well, one Minute of Subtitles is enough to search for a way to change the Language.
At least for me.

I'm hoping they add an option to select the language of the subtitles with the upcoming update, especially since it's supposed to include full sound and dialogues.
I would much rather play with English subtitles, than the language of my OS.

I know this is like 3 years late, but one day, some connoisseur of crappy games may find it useful. So, if you want to change the language you should press Windows Key + R and type in:

%LOCALAPPDATA%\Moon\Saved\Config\WindowsNoEditor

This will open a folder where config files are located (you need to run the game at least once)
Then you need to edit GameUserSettings.ini with a text editor.

And add the lines:

Where en is language used. Generally, the first 2 characters should be enough, with some exceptions like Traditional Chinese vs. Simplified Chinese.
Here is one of the websites I've found on the internet that lists the most common combinations:

Also, I have written it down on PCGamingWiki to make it easier to find.
