This looks very similar to "Shadow Physics". If you have not seen the game, it was shown off at GDC 2009 (http://www.youtube.com/watch?v=Bb5DjyoDObA). It got a lot of attention and then 3 years later was canceled. Here is a video of the Failure Workshop from GDC 2012 describing what went wrong (click on -> What Happend With Shadow Physics Intro): http://www.gdcvault.com/play/1015751/The-Failure

I hope the developers can get past the initial "Wow" factor and actually make the game fun to play.
