I cannot disagree with your opinion about the author of the game, although I am also from Russia.
First, it disappears for 2 years, and then an update is released in the build, then within a year it develops a new update again. But don't forget, he's working on two major projects at once, I'm talking about his other game, which you play as a girl. I also heard somewhere on one of the forums that after the 29th update, he stopped working with a translator and a programmer, who helped him a lot in working on the game.
Therefore, he is currently working alone, on two projects at once, so he can be forgiven for not meeting the deadlines for the release of the update. In addition, the game is now completely free, with the voluntary support of the author and no previous access for money.
Although I still don't understand it, why say deadlines if you don't meet them.
