Game: Polygon Storm

Polygon Storm, the intergalactic geometry dodger from Glass Knuckle Games is a pretty interesting concoction. First try to imagine a minimalist's take on the "bullet hell" genre. Now strip away the bullets (yes, even your own), throw a little bit of Asteroids into the mix, and replace your starship with a vanity mouse cursor from some old shareware disk. Wait, I'm getting ahead of myself with that last bit. Those sparkly contrails emanating from the rear of your craft are one of many unlockables granted as you play. As a matter of fact, the entire game is built on a foundation of unlockable content, and I mean this quite literally.
