Most of the branching scenario exercises I see are built using Storyline or Captivate. But Christy Tucker created one using Google Forms. You can check out the scenario here, and read about how she created it here.
This version of a branching scenario is fascinating because it is so uncommon. This could work as a very minimal e-learning design or a prototype. If it is being used as an e-Learning object, I might add photos or videos to most if not all of the questions. These can provide brief videos of recorded interactions, or still images similar to what you would load on an e-Learning scenario slide.
