Translation project by volunteers exists in “transifex”.
However, because this project was billed for usage fee and the leader was not a related person, decided that it is difficult to continue with paid project.
Also, there seemed to be no time to contact with you.
I found this site and confirmed that I can do some translation work.
However, it seems that the program for actually applying the translated text to the game is not currently available.
If you implement the necessary measures for this project, in many languages, you will be able to greatly reduce the burden of actual translation work with the help of general players.
