A downloadable game
Use your iPad's back camera to take a photo of a real-wall.
Hold your iPad against the wall to begin investigating the real-wall for any cleak and potential leaks...
When cracks appear and leaks happen, use your fingers to block up the holes! This game is much easier with friends and more fingers/inputs. :)
If too much water leaks; you will lose!
If too much oil leaks; it will block your view.
If too many leeks leak; you can either laugh or not. :)
