What could you have possibly done to make the monkey so mad? Temple Run 2 (free), much like its predecessor, is insanely addictive and madly difficult. Yes, you’re still fleeing through a sparse, badly maintained network of paths, using your fingers to slide, leap, turn and tilt. These sorts of games have a definitively juvenile feel; but really, the free game (for iOS and Android) is a great time-killer and not that embarrassing to be seen playing, a sort of intense form of snake. The truly addicted will be pumped for better graphics, new obstacles and power ups, and even great new achievements… the rest of us will simply growl when we slam into that damn pillar for the tenth time.
