How do you go about creating 'restricted' menu access for 5 individual scenes in 1 project. Meaning, student may attempt scene 1, 3 & 5 without completing scene 2 & 4. However, I still wish for each scene's menu to be restricted. Student will be e- rewarded for completing each scene and then also given an e-certificate of completion once all scenes are done. Any words of wisdom are greatly appreciated.
