I want to build a clickable mockup for a game tutorial, i.e. a series of screenshots the user can go through to simulate the tutorial. The path through the mockup is non-linear, e.g. at one point the user can decide which of two quests to pursue. Building the mockup is not a problem, I've identified Pidoco and Axure as possible tools for this task. However, I want to track each users path through the mockup and I couldn't find out whether either of those or some other program has that capability. Basically, whenever the users clicks a link between two screens, both the origin and destination screen should be written to a file (ideally a csv) so I can later analyze the sequences in which screens are clicked through. Does anyone know of a software that has this capability built in? Ideally, the prototype should be testable on a mobile device, like in the Pidoco app.
