Hi,
Currently the game is available in 18 languages, English and Russian included, although keep in mind, that all translations are done by people who volunteered, so it might not be perfect.
Dev doesn't do any checks on that, so if you'd like to submit any corrections feel free to join our Discord server, find Russian translation thread and post there.
To play in your desired language, simply in main menu go to settings and choose a language from a drop down list.
Hope this helps,
Cheers
