This is the game that we made at the 2nd annual Global Game Jam (Jan 29..31, 2010). The theme was Deception.
As a incorporeal assassin, you possess and control the bodies of innocents to further your mission of destroying rival assassins. It’s a networked multiplayer action game, where you attempt to deceive the other players into thinking you are just one of the masses, while trying to spot others when they slip-up.
The theme for this jam was Music Video Games, to come up with a game idea based on or inspired by a song (note: not creating rhythm games).
A little girl goes for a walk. When the sun shines on her, she is happy and spreads happiness to all those around her. When she is in the shade, she is sad. You control the sun, who wants to make the girl as happy as you can. You do so by positioning the sun so that the clouds beneath you don’t end up shadowing the girl.
