The concept is easy (and maybe not a game at all) – your mission is to “infect” as many pixels as possible with the “bacterium pikselum”. The bacteria breed, by looking at them with the iOS-camera. Give them food by taking them to an edge and start moving the camera along the edge. What I like about this concept is, that you do not need any QR-Codes or something other prepared, to step into the “Augmented Reality”-world, but that the “game” plays instantly from any phone in any environment.
Before “Piksel Bacteria” And-Or raised gameplay and reality questions in works like “Gamescape“, where the players input of the game results in architecture. Or Discrimination Pong, a work that raises questions about gameplay modifiers, asymmetric gameplay and discrimination.
