Oh it seems like some problem with Russian keyboard. Key "/" is some other key that make game crazy. We somehow repaired it but then break again.
(oh, i just noticed this old comment).. hey, in case you didn't already see it, the latest update to this game has customisable keys and also FPS capped at 60, so hopefully this will solve these problems! if you try it i'd be very interested to know if the keys customiser works properly on Russian keyboard
