Learners need to know to go back and answer the question correctly before moving on

I created a Storyline game that does not allow the learner to move on until all the questions in each scenario are answered correctly.

Each of the scenarios do not let you move on to the next without going back into the questions that the learner missed and correcting them. 

What's the best way to let the learner know that and how can I set that up in my Storyline 360 course?  https://360.articulate.com/review/content/12dd6a15-7259-4aa2-a930-09ea793ac09d/review
