What's the fullscreen button? It sounds like it doesn't require uploading the game again, but I didn't find much about it after ~2 minutes of searching for it.
I think the second lesson in chapter 14 should remind the user about the order of operations in one of the errors or hints. That lesson really confused the past me specifically because I didn't understand that my code wasn't written in the correct order, and there were no reminders of its importance.
