Across from Subatomic Studios I ran in to Sam from InstantAction. He showed me an early development version of a game his company is working on called Flipt. The game plays a lot like Shift, a platform puzzle game where you can shift the game world back and forth from black and white to change the platforms you're running along.
Where Shift had a button to invoke this change, everything in Flipt is controlled via the accelerometer. Both Shift and Flipt are hard games to describe, so check out this video I took of the game on the PAX floor. Thanks to the terrible lighting and being bumped around by the crowd, the video quality isn't the best:
Flipt is still in development, and a lot of the animations and sound are just placeholders. Regardless, it looks pretty cool and we look forward to seeing more of the game in the future.
