The game concept is interesting, but I'm going to have to drop value for the over ambitiousness of the actual combat in the later game.
Flash can't handle that much stuff on the screen. This game has the same issues other, initially good games have, of cramming later battles with too much junk. Trying to get through the 9th ship battle was impossible because the game froze. You need to either set it up with fewer nodes per battle, or less ships that fire at every single player owned node in the late game.
Furthermore, the APM requirements to win with anybody who can't insta-win, or use shields to hold nodes, gets rapidly into the annoying stage. (and incidentally, this makes the combat girl the worst one in combat)
