Thanks to a super nice and diligent translator (Clavik1), The Last Secret is now fully available in Ukrainian and Russian! The previous automatic translation has been replaced and you can now fully enjoy the game in these languages.
What? You're not speaking any of these languages? Well, then you can at least enjoy the improved editor at the true ending of the game and numerous bug fixes!
So why not give it a try now? It's free, and waiting for you! :)
