Possibly I found the game.
From The Lost Media Wiki
As the title says, I possibly found this game, I mean, it wasn't me who uploaded it, it was a user called "Vovanglew-45" and posted it on gamejolt (https://gamejolt.com/games/kusogovnokuso/785536). Is this game real? I don't know, I downloaded it and it seemed to work even though I've never played the original but somehow the game seems to be in Russian. But well, if this is the original game (albeit modified in language), it's already a good advance that it hasn't been completely lost.
