1. "much"
2. I didn't know that, but that still means the game is in limbo. It's not being completely left in the dust, but the amount of progress being made is small enough that it's not unreasonable to question if it will be abandoned or not. (I don't believe so based on what you said, but that's just me.)
3 (Bonus). Ngl, I'm kinda pissed off that of all the people ranting and raving about the lack of progress and damn near telling the dev to "suck it up" in response to health issues slowing progress, the one you choose to go after is me, who was literally just the messenger. Maybe I'm reading more aggression from that first sentence than there really is, but I'd rather not have knives at my throat for relaying information I can't presently verify with utmost certainty.
