SpyPug is a concept for a HTML5 mobile game similar in gameplay to Flow, where the user connects various matching points on a grid by drawing a line. Unlike Flow, in this version various obstacles appear on the grid itself, presenting timer speed ups and slow downs, instant deaths, loss of points, and other variables. The visual style is inspired by 1960s and 1970s spy technology and computer interfaces, with a fun cartoon animal rivalry between SpyPug and his feline nemesis, Dr. Bad. The actual game is scene as if it is from SpyPug's all-purpose spy decoder device screen, where SpyPug can disarm bombs, unlock doors, hot-wire cars, and other spy activities.
