Having only one language for the game is actually on purpose. It allows me to move much faster with new content and updates, without having to care / test translations.
There's no plan to add more languages :-(
Hello Andy,
Can you add some tools for loading language packs from file or web? You can give a format for these packs and shortly explain how it works and community well be supporting these packs ourselves.
Good idea actually! But the technical problem is currently the font rendering, which are baked texture atlas fonts. So most translated texts wouldn't be displayed.
I'm not a native english speaker as well, but I always change the language of those kind of games to english (if that's the developer language), mostly because translations are not very accurate when it comes to gameplay relevant descriptions.
