Attention, angst-filled teens and Atmosphere fans: your favorite mobile game has finally arrived. One Single Life is as accurate a title as you can get.  In this iOS game, you get one chance to play; when you die, the game is literally over. On each of its 10 levels, you perform a single all-or-nothing jump—clear the jump and you get to move on, fall and you won't be able to play the game on that same device again. This type of mechanic makes for a harrowing and nerve-wracking experience, which puts a hardcore twist on what on the surface appears to be a casual game. At least the app is free, so you don’t have to worry about getting your money’s worth. [via Pocket Gamer]
