Even a % done post now and then would keep hope alive for this game.
This game to me has held the same fate as A Second Face part 2 (from AGS Forums), Indiana Jones and the Fountain of Youth, and other games which I might not have mentioned, in which it seems that discussion of updates all but stopped. (I used to check more frequently over hopes of news. Now I only check every few months when I happen to think about it.)
No one really knows how far along the project is. I know that the volunteer team for this project is doing the best they can, but a progress update would be nice. After all, a lot of us who were drawn into your free game are the same people who would be paying for your paid games.
