Gravity Ghost swirls through Steam's solar system today

Ivy Games' Gravity Ghost is on Steam today for PC, Mac and Linux for $15, a reasonable price for a trip through the stars. Plus, it's two-for-one, forever – pay $15 on Steam, get two game codes.

"Why?" Gravity Ghost Designer Erin Robinson asks in an email. "I'm encouraging everyone to give that second copy to someone special in their life who doesn't play video games. My hope is that it will open the door to this amazing hobby and allow people to share that joy with their loved ones."

Gravity Ghost is a physics puzzler with a twist (or a twirl): Players soar around planets, using gravitational pull to gain momentum, alter direction and collect pieces of a shattered galaxy. There's no "fail" state, though there is a rich story with hints of darkness, plus voice acting by Ashly Burch (Borderlands 2), Logan Cunningham (Bastion) and Sarah Elmaleh (Gone Home). The soundtrack comes from FTL composer Ben Prunty. See the story trailer after the break.
