Ok so once in a while something comes along on mobile that has me freak out and tell all my friends.  And the latest app to get this much attention and acclaim is Windosill by Vector Park. This is a great example of interactive story telling that combines narrative mechanics in the most enchanting and engaging of ways.  Its hard to describe, and watching a video of how it works will ruin all sense of discovery and exploration. And that’s part of what makes it so rewarding to play with, as while its never clear from the outset what your goal is, every little experiment you try along the way leaves you with some sort of result that offers clues, no matter how subtle. In fact, the less you know about this app before you see it, the better.  Get it NOW.
