Haha, yeah, but that post was from when exactly? That's right, March 5th. A day later he posted an update, and since then it's been radio silence. That's 120 days (3 months, 28 days) of GB not posting anything. Sure, 120 days is an amount that's reasonable for making such an update, but not for being silent.
Again, I'm all for hope, and I'm really hoping that the game is still in development, but the silence is just odd and troubling. The arguments for why he wouldn't be working on it are getting stronger, the arguments for why would still be working on it are getting weaker : /
But it might as well be that GB is just ill, or dealing with personal stuff, and that GB just picks up development later, and everything gets delayed.
