This little gem is probably little-known, but was one of my first Amiga games ever. SideWinder is a little vertical-scrolling Shoot 'Em Up, that is not as fast-paced as e.g. Silk Worm or SWIV and therefore appears easier but is still far from boring.
You lead off the fight in a futuristic environment, something that looks similar to a circuit board. So either your spaceship is really small or computers of the next century will be gigantic.. and as if this was not enough, they even shoot back!
All things considered, this game is pretty solid for its age. Little gimmicks, like the digitized sound of explosions and an outstanding intro theme by David Whittaker make this shooter worth a try.
Check out this youtube video. It features the cracktro, intro and some gameplay (at around 4:10 min.)
