Steam Translation Server is a thing. But then I won't be able to take part because of my limited account. I'd like them just to send me some editable file and I'll do all the work on my own. Just like I've translated this game. As for now, I'd like just to be able at least write text in my language in the chat.
Could it be Tiny Miner?
