I did buy this theme to learn languages I don't know yet, and it looked like a good thing have the same code translated to multiple languages to compare and learn faster.
But, do I have to download it one by one, lang per lang? I'd like it to download the full version and recieve the full code if the theme recieves an update.
Yes, sure. You can get it from Github by providing us with your purchase key from https://1.envato.market/EA4JP and your GitHub username.
