Yes he has! We have our developer panel that we followed almost all the time lol, in it I saw that the number of visits to the topic that converted into downloads was a relatively good number, very similar to our first game "Class 5B"
However, the number of people who saw the game is absurdly smaller, while the class reached, say, 5000 people in a month, the backroom didn't even reach 1000, which means that it appeared in the feeds of far fewer people.
