God DAMN it!
I won; and after about 25 tries what do I get? A screen saying "you have won"; I guess I don't know what I expected, but this is a really hard game and I felt so happy only to have it be a big let down. I wish there was a little video at the end or something funny or even something purposefully lame like the certificate in Incubus Pulsum.
Anyways for others trying to figure out how to beat it; it's a little bit luck honestly; but here's some pointers:
-The most important thing I learned is spread your buildings out all over the planet; you won't really be able to defend them all, but at least you won't be crippled by a single blast; it will only destroy 1 building.
-build a bunch of mines right away, at least 3; I usually do 4 and then take a little damage
-you can take damage for the first 10 rounds or so, although you want at least 1 or 2 guns if not more
-don't bother trying to teraform quickly; I never got it past 75% before being destroyed when I tried that.
-get the obliterator as fast as possible; by far the best weapon in the game, also the smart missiles are good.
-never upgrade to the third laser, and really I don't feel as if it's worth the second one either; I couldn't even support 1 lvl 3 laser alone with 7 power plants.
-You want at least 1-2 hospitals and workshops from the begining
-farms suck, but you need them; remember to spread them out
There's also some serious glitches with this game; I've had the initial teraformer cost 800, 1000, and 1200 in different games; I wonder if it's related to what you upgraded it to in the previous game or not. The power plants seem seriously glitched too, sometimes it seems like I'm always at max power and then a second later I may be at like -30 power. Very confusing.
Good game all around though; I really should have done homework instead though...
