Really well made game, and fun, though it does need to be longer. And to drega, making money's not that hard, just fill up most of the bottom row with economic centers, and the money comes pouring in.
UltraMagnus, you have to get both types of upgrades for both the uzi and rifle. Uzi has an assault rifle and shotgun upgrade, and the rifle has two different ones as well, have to upgrade both.
Weird that so many people don't like the rogue. By far the best damage dealer for non AOE attacks. Fragile doesn't matter when you can take out most enemies with one hit. AOE is nice to soften things up, but when you need to take out a particularly annoying enemy right off the bat, there's none better.
