Graphics were nice top-down vertically-scrolling space/airplane shooter with some layering/parallax effects. Gameplay blew me away because it was the first time I'd seen something where you could only have one power up at a time, you had to jettison the current one before you could pick up a different one. Each section of the scrolling map and the enemies there were of course vulnerable in varying degrees to the possible special powers.
