The design of Retake/Review is this: the Retake button remains active as long as you do not use the Review button. Review button should only be used when all Attempts on Quiz level are exhausted. To prevent that the user is confused, I recommend to drag the Review button under the Retake button (can be done on the master slide for the score slide).
The Continue button will launch the actions you specify in the Quiz Preferences On Success and On Failure. But the last action will only be executed after the last attempt on Quiz level. Since you have Infinite attempts, the action On Failure will never be executed, the user will never be able to get on if he doesn't pass the quiz. Is this really what you want?
