A small but very important update today - we've added Russian localization! You should now be able to select Russian alongside the other languages, and it should default to Russian if you system language is set to Russian too.
So, for our Russian players, Здравствуйте! I'm sorry it took so long to get this out; next time, Russian will be a much greater priority.
There are also a few minor bug fixes, and the game should be running pretty smoothly for you now.
Feel free to leave any feedback in the comments or in the forums.
