clickable prototypes> map every possible pathway?

I am building a clickable prototype of a mobile game in balsamic for a client.

Do I have to map every single branch option? If so, the home screen, for example, would have many different states and will all need slightly different return screens depending on what is clicked.

It would be easier not to make every option clickable and just demonstrate one pathway per function. More of an interactive demo or tour I guess. But that isn't a true representation of what the build will be. (the real build will have multiple clickable options for the user).

Hope that makes sense.

Thanks for any input!
