No, it hasn't been released yet (January the 3rd is the day to remember)
It is now for sale! mdna-games
I thought I'd open up a thread for any help seekers that will come along.
I have just completed a video walkthrough, and here it is. The Birdwatcher - Walkthrough
If you watch it at fullscreen, it gets a bit blurry. The file would be enourmous otherwise.
I know many prefer a written walkthrough, but I personally can't do that, so this is the best help I can give.
Of course I can answer questions as well, so if Mikael isn't here quickly enough, I will try and assist.
