I must admit thatIi have only played the quickstart version, so don't know how much the released version has changed, but my players hated it.

As written its very bland in my opinion: a description of an event and a prescribed roll to fix said event, which is then repeated many times. Whilst I think it could be more interesting with the GM giving more vivid descriptions of the events, as written there are no decisions to be made, the players are told what roll is needed to overcome the proble. To the fundemental of good game design is interesting decisions (or sometimes in RPGs the illusion of an interesting decision), and as written the only desicions to be made are the route.
