I hear you. I would have added many languages already but it's just too much work for a one person team. I'll get to it eventually, but it likely won't be soon. Sorry about this.
Getting the translations isn't the main challenge--though that's tough too--it's the implementation. The font and UI elements need to support all these various languages. Plus I'd need to provide a way for to players to change which language is shown and save that setting. Even getting the game to a point where players could mod the game to have different languages is a lot of work.
