We conceived and built Geese Squad as a native iOS app with Cocos2d framework and Box2d physics. It uses the device’s accelerometer to steer a chevron of geese on their winter migration. Players pick up loonies and twoonies, blue berries, maple sugar and other geese. Players also must avoid wacky golfers, rock-throwing kids, airplanes, American eagles and the occasional Avro Arrow. Players can soil their enemies with the only resource that flying geese have.
