Game Boy Port of Crystal Quest.

Buckle in and gear up for the classic galactic ride of your life. Far beyond known galaxies, the stars are scattered with precious crystals. As a renegade outer space prospector, your job is to scoop 'em up and bring 'em home. Just one problem: The brilliant glow of these gems attracts some of the universe's foulest pests. We call them nasties - and they're just that. So go ahead...zap the intergalactic vermin and cash in on the crystals. It's nasty-blastin' fun.
