The guy sounds way too whiny to me. His idea of "game design" seems to have no intention at all.
Also, as he mentioned in the video, he made the game so that females had to provide milk to all humans. While an interesting idea, it's completely useless for a game environment. "Oh look at me, I'm being artistic because I added boobies!" To me, that's just lazy. It's tipping over the line to look edgy, which in my opinion, is completely unnecessary.
The game design looks lazy too. "You do nothing, that's like real life." But that's not what makes a game fun. You might say you added story, but the problem is - how do you develop story when there's no gameplay to develop it with? The guy just looks like he's taking it a tad far to justify already dead arguments.
Overall, however, it looks okay as a game. Nothing I'd want to play, but it needs some serious work before it's anywhere near good. I also don't think that people need to bash it a ton - where McJob isn't, the bigger problem is the backlash to the general criticism - but I wouldn't say that it deserves any title higher than "okay".
