Today’s free iPhone app at FreeAppADay.com is Shift, from Armor Games.
Shift has been available as a flash game on the Armor Games website since 2008, and in that time has been played over 2 million times. The game is a puzzle platformer of sorts that challenges you with making your way around obstacles like spike bits and raised or lowered platforms and into a doorway to complete the level.
To do this, you’ll literally be able to “shift” the black and white environment almost entirely at will (with very few exceptions, like when shifting would place you in harm’s way or send you through a movable object, like a locked panel that will eventually open). That is, if you’re, at one moment, standing on a black platform with a white background you can flip or switch the environment vertically, so that you are now standing on what was once the white background as a platform, with the black as a background.
Shift on the iPhone contains all of the levels found in the original flash game, plus 25 new levels only found in the iPhone version of the game. If the game sounds interesting to you, make sure to download it while it’s free today.
