Changing the language from Russian to English in the start menu doesn't seem to be enough, you have to close the game entirely, then restart. There's some kind of flag that doesn't get properly turned on until you do that. Otherwise, you get random Russian instead of English dialogue here and there.
It isn't even properly translated. There are multiple scenes in Russian. (I gave up after multiple scenes in Russian, can't play a game when I can't bloody read WTF is going on) If you can't even be bothered to makes sure a tech demo is complete, how crap is the future iterations of the game going to be? If you best foot forward is half assed, this game doesn't stand a chance.
Oh, lord... Do you know how to read? This wasn't the dev who uploaded... Probably leaked from his Patreon... And he's a seasoned developer, so he stands a chance... Tip for you: if you don't know how to read situations, you don't stand a chance in the real world...
Let's just say, for right English translation you not only need to turn it On in Setting menu, you also need to restart the game for it properly to work(change localisation).
Guys, let's just end this problem with English localisations as it not happened, just restart your game and it will work normally!)
