Ah, Call of Carlos is a free "Tilt+Tap" game and it is wickedly addictive, all you have to do is tilt and tap your way to the exit before the growing lava gets you!
Oh and you have to get the diamonds along your way to gain more points!
I think it might be the best FREE game on Lumia right now (more will definitely come).
