I don't see what you guys are crying about. Game's perfectly simple, if you know what you're doing. Shoot enemies. Shoot them some more. Buy the biggest, baddest ship you can. Rinse&Repeat. Unless you're on planets with 20 defense, where you buy the biggest ship you can first, THEN, shoot enemies, shoot 'em some more, buy the ship, and rinse&repeat.
Mm, first of all: Doesn't Radalph, or however you spell his name, just look absolutely great in that armor and what looks like a black Metroid for a head?
Second of all; I'm loving the security demons.
