Some neat things going on for an early 1982 shooter.
Ride of the Valkyries in the background is cool.
The sprites are multicolored and move smoothly.
A couple of complaints. The enemies bounce of the sides of the screen. Should they be bouncing of the sides of the screen when we're in vast space as implied by the scrolling star field!!?
When you lose a life, you start over?! Yuck!
Still, a solid B.
