Now here's an inventive concept.. It's an survival adventure quest where you actually run in the real world (with shoes, sweating, and the rest) to progress the story.
Even though this is a runner game in it's truest form, I feel they are somewhat mislabeling it here as 'runner' games have taken on a completely different meaning in the app store. (see MegaRunner -- http://bit.ly/x8tN8G
Never-the-less, this is something completely refreshing. I don't know of anything else like it. And now that I think about it, I can't believe it's taken this long this long for something like this to come out.
