A six-minute gameplay video along with some commentary on Swivel.
It gives more information about the game and shows it off running on the new retina display. Sorry it's a bit fuzzy — I recorded it with my camcorder since the iPhone 4 simulator runs too slow on my iMac when you crank up the HD graphics (crazy, I know!). The game still runs a smooth 60 frames per second on the device though.
Discussed are the updated HD graphics for the retina display, the new gem blocks, the control scheme and a few other bits and pieces.
