I get where you're coming from, but it's been half a year. Kickstarter Backers contributed more than 10.000$. The author has an obligation to them, and bimonthly updates that aren't even regular just don't live up to that obligation. I'm not even talking about having to speed up the progress, just about posting "Sorry, didn't really get anything done this month." once a month. Besides, nobody is accusing them of not caring about keeping the fans notified. Quite the opposite, this thread is full of people just wanting to support the author.
