Apologies but we got no control over that, we don't make those and I have little to no proficiency over that language.
I understand, the truth would have been great to be able to play in Spanish unofficially, currently I finished book 1 chapter 10 that until then they managed to port the game to my native language (Spanish). I greatly appreciate how they develop the game, I really love it very much and I would like to see many more long-term releases, successes and keep it up :D
