I've been spending an neourmous amount of time with the game and have to say it is one of the best on the iDevice. The controls could be better, but are manageable enough.
Oh yeah, the hunt for the blueprints starts getting on my nerves. I completed the game already and only found little more than half.
Also, anyone got the deal with the hidden sectors? I got some coordinates and went there, but they turn out just to be as common as any other sectors out there.
