No, it's enough that he's actually doing something. Some devs keep promising dates and never hitting them. Karabinek isn't as talkative as other devs, but that's fine. Those other devs spend more time giving deadlines they never meet than they do actually working on their content.
Doubtful. He literally said it wouldn't be done until after the New Year.
When Karabinek says he got injured and was incommunicado, I'm inclined to accept that explanation. He's not BrainDrop.
Odd thing is, the intro scene to that game is almost an exact match to a scene in The Assistant (husband walking in on his wife getting strapped by her boss from behind with some dirty talk). I wonder if it was a homage, a ripoff, or the same person involved in making both games.
