Vector takes its cue, in style as well as the basic concept, from Canabalt, the endless runner that popularized the genre. So in Vector, the main objective is to run over a series of rooftops without stopping, tripping up or falling into the abyss, just as in Canabalt. In the same way, the look and feel of both games is very similar.
With regards to Mirrors Edge, Vector borrows both from the basic story and from the use of Parkour as the means to escape from the authorities. Not only is the main character is an unsung hero that uses the same type of movements to escape the authorities, but the authorities are an oppressive force in a not too distant, dystopian future, to which our character is trying to add a touch of color.
