This is the only game I ever bought at the Alawar store a long, long time ago.
It has some messed up activation (Registry entry), I kept the codes until today.
It's not the best shoot'em'up I ever played, but the for the time modern presentation and good controls made it quite entertaining.
It has some technical difficulties, like not having a full screen or borderless window mode, so you'll always see your desktop in the background.
It's fun nontheless.
