Game: Pumping Heart
The game tries, in a comic way, show the importance of donating organs. Telling the story of an accident with a organ donor who which you have to help his heart to someone who really need it.
Backwards: One or more aspects of the game works the opposite as would normally be expected: maybe the controller is reversed (left is right, right is left), maybe you win lives every time you die, maybe it scrolls to the left and your character moonwalks.
Bigger Picture: The game touches on a political, environmental or social issue.
