Line Runner, a new app available for the iPhone is currently free of charge for a limited time. It is developed by Robert Szeleney who also made the successful app Stick Stunt Biker. The point of the game is to jump and roll over obstacles as the screen quickly goes through a variety of courses. This mobile app features 10 different tracks to run on with the chance to get as far as possible on each one. As the tracks go on they get more difficult and the obstacles come faster. While the beginning levels are still considerably difficult, the harder levels are near impossible. Compete with other players on the Openfeint international online leaderboard and compare high scores. It is an addictive game that will help easily pass time filled with boredom. Act fast while the app is still free to download as it is likely to be between one and two dollars.
