Good game, but gets boring in a weaird kind of way - the last levels are not a match at all, anyway - 3/5, because I have the bug with the Social Network Badge as well - I finished the game and didn't get the badge.
+ two more things - great idea to NOT allow using missles vs the last boss AND why the hell do you have to fly for over 2 minutes on a empty screen untill you actually see the boss? What is the sense, the purpose of this? Man...
Would be better if I played Minesweeper than this game, un-cool... 2/5 for the sense of humor author had sticked into the game, that's it, no entertainment at all...
