You could call game designer Erin Robinson a triple threat , except that doesn't adequately encompass all the things she does well. Robinson draws with impressive skill, creates spirited animation, comes up with clever mechanics and breaks down game design theory and practice with inviting ease. Most of that gets displayed in the demo of her in-development game Gravity Ghost, which takes the concept of proportional gravity and melds it with a few other intriguing ideas.

I like what I saw of Gravity Ghost at E3 because it feels approachable in a way that hints at further depth. Watching the game work really makes it feel like there's a tiny universe inside that laptop, full of physics rules and creative recombinations waiting to come to life. Loads of other games shown at gaming's biggest expo could learn a few things from this indie title.
