We don't intend on translating it, unfortunately, because it would halt the game's development for months. It is not viable for us to dedicate all that time to it.
That said the game is licensed under Creative Commons 4.0 Attribution, so people can make translations if they so want — although it wouldn't be a smart decision at the current stage in development, since we still at times go back to old content to polish it. The poor translator would suffer a lot trying to keep up with us!
