Starting from version 0.8.2 you can create your own localizations. You can send your own translation files so that I can add them to the new version, or so that other players who speak the same language as you can play in their native language.
There are two files (.json and .xml) in the Ghostophobia Classic_Data/Translation/ directory, meaning there are two ways to translate the game.
The video below shows how to translate the game.
There is also a file with instructions in the directory.
Important: If you use a .xml file for translation, then the .json file needs to be renamed, and vice versa, if you use a .json file, then you need to rename the .xml file.
Example file names when using .xml: "translation.xml", "translationNOT.json"
Example file names when using .json: "translationNOT.xml", "translation.json"
