Currently only English subtitles are available for the DLC.
The entire 24 language subtitle set for the original feature film was made possible by a community-driven translation effort. It's was a pretty big undertaking with volunteers all over the world helping make it happen.
We may add more language to the DLC in the future. If you are interested in helping, please feel free to contact us at IndieGameTheMovie.com[indiegamethemovie.com]
But in the meantime, we hope the English Subtitles help out a lot of you.
Huge thank you and shout out to Adam Saltsman [finjigames.com] for help with the App and Update!
Thanks so much for reading and checking out the film!
