As much as I would like Alder to come back as well, I think we can all consider this a dead game. Most people working on it have left it I believe in order to move on to other projects and Alder has made no inclination of coming back at any given point.
Unless Alder specifically said that someone could adopt the game, something I doubt but am still hopeful for, the game is on 'hiatus' for an undetermined amount of time. most likely forever.
I'd like to give Alder some supportive words or such. I'd also like to give them money, but I don't have money, really. Miss this receiving updates. Still, was nice while it lasted.
