HOW TO CHANGE LANGUAGE!!
i had the problem that from the second i launched the game it was in vietnamese for some reason
the dev recommends removing your local file or something but i aint grinding all them points again
so here u go

open the menu
click the third option for settings (the one above discord)
click the third option again for interface
the top option should be the language (press the arrows and see if it says any other language name)
press the left button on the bottom of your screen for apply

TADA
no needing to remove ur save file
