Tilt to Live recently got an update that includes Game Center support and Retina-worthy graphics. You can grab the game (if you aren't already an addict) here. To learn more about this addictive and award winning game, see my Top App picks article here... I am loving the sharper game screens even as I write this. Shoot, no new power-ups though..! Well, it's rumored there might be another present in time for X-mas!
