Too Hard!
The game is really cool, but it's too hard. I'm playing this at N00blet difficulty and the freakin' aliens always kill me at approximately the same wave, if the waves didn't consist of so many ships it'd be a tad easier. But over all it's really fun and cool!
Ps: the structures are too big, it feels like you can't really organize where you want to put your bases comfortably.
