FatLab Music has released Snowferno, a new App Store game in which players guide a snowball through the center of the Earth and out of the other side. Twenty puzzling levels feature switches, boxes, gears, moving platforms, swinging hammers, and other objects. Fire and snow piles make the snowball smaller or larger along the way.
Snowferno uses the accelerometer to control the snowball's path, while the on-screen controls handle speed and camera positioning. The game sells for US$1.99 and requires iPhone OS 2.2.1.
