This game is epic. I thought it was waaaay too hard. Then I realized you could pause. Now I don't have too much of a problem, beat most maps in one or two tries. This game demands good tactical "team" construction (Certain types of games demand different combinations of fighters, turrets, and other stuff), forward thinking base construction (it's the most frustrating thing in the world to be stuck in a loop, with both your fighters and the enemy fighters unable to break through to the opposing base, as there is no "delete/ sell structure" button.) and understanding of how to efficiently use your energy (I actually use mining ships a lot later in the game). The game is quite difficult but rewarding, and unique enough that I feel this is one of the best flash gaming experiences I've ever had. Only problems I have with it are the lack of a way to remove or move buildings and some of the black hole maps are definitely way too hard. The difficulty should be decreased a little bit, especially in the maps with the infected. Solid 4.5, maybe even a 4.75
