The result is well done, very atmospheric, but a little difficult if you do not know the book and, unfortunately, too many omissions. You would have to make good a 2 CD version of it.
The substance is in fact very good! Internet game and reality woven into a puzzle together, super idea!
The star deduction therefore only that you have to listen to the radio play several times until you get it all there. Here it is recommended, in addition to reading the book. :-)
Overall, a 2 +.
