@SilverSonic105: I would say that blaming the game designer for having a kludgy interface is fair. I think that since there is no point in not saving, there should be an auto-save. :Þ
I'd recommend not letting enemies escape except off the left side of the screen. Top and bottom escapes feel unfair. One life, no save/continue is a little frustrating. The animations are nice, and I like the weapon/ship upgrades. Spelling is an important aspect of presentation though. Overall a decent start, but needs work. 2/5 for now. I'll watch for updates though. =)
