2 years later and I still visit this...
Do you think it is possible to show user a kind of menu choice for choosing language? After label start, before the story begins?
I think you could use the same script bit currently included before the menu, just edit it a bit so that it's after the game starts but before the story begins and take out the
renpy.utter_restart()
and/or add it to the "options" menu. It may take some tweaking. If I recall correctly I saw something similar on lemmasoft forums, I'll check my bookmarks for you.
Also wow, 2 years already? Gosh I'm behind on stuff I wanted to post here, lol.
Anyway I think I found the post I was thinking of:
