I can't figure out what the hell to do on the last level, all I seem to be able to do is maintain the initial 9 stars, the minefield to the right, and one of the mine stars to the left, beyond that, I'm completely stuck, too many defensive stars, fighter bases immediately recapturing anything I blow up with missiles... I'm at a loss here.
Inability to change skills makes me find this game to fail. Decently done in general, but one poorly picked skill early, and you end up having to start from scratch because the first boss can one shot every one of your buildings.
... I must be missing something, trying to achieve either the 'get to level 9 without shooting or dying' feat, and the 'finish level 12 without moving' feat. How are either of these possible? How can you finish a level without killing enemies? Is there a hidden timer or something? And how do you take out the shielded enemies without moving?
