For some reason we seem to still be unable to upload our game to GGJ site. Here is a download link of our own instead:
and a youtube video of playing it: https://www.youtube.com/watch?v=40WvvJRgQ0A
To actually play the game you need quite a specific kinect+projector setup. Short instructions included in readme.txt in the 7z, and a setup.jpg to show what our setup was like.
And yeah, seems we were confused many times if the name was Hyperdrive or Hyperspace Crashdown... :)
