Difficulty?

@gavinruneblade you'll figure it out soon. A lot comes down to luck of the drops. I've had games where I got a death ray in the first world and others where I've gotten trapped by an EMP and killed on turn 3.

Having beaten the game quite a few times on hard, I can tell you that getting past the first world can often be the hardest part save for the very last level. Right now I win roughly 1 out of 4 on hard and in most of the cases that I fail, it's because I make a stupid mistake on world 1 that costs me the game. Once you get your first reinforcement it helps a lot.
