Feedback: Using Variables for The First Time Demo

Fun project! Though I think it needs a non-fiction path. :-)

Here's one issue I noticed: I couldn't click the word "Submit," but I could click the image of the book. I assume that's because the trigger is just attached to the book image. Or the book image and the text might be grouped, but groups don't always behave the way you expect. 

Here's a solution:

• Create a text box (or shape) with the word "Submit," and give it the same size/aspect ratio as the book. 
• Go to Format Shape>Fill, and fill it with a picture (in this case, your image of the book). 
• Go to Format Shape>Text Box, and adjust the margins as needed so the word appears where you want it. 

This is part of what I call "group therapy." For interactive elements, I think it's much easier to have just one object to deal with, instead of multiple objects that need to be grouped.

BTW, when editing states, you can insert or paste additional shapes, icons, etc. within any or all of the states. For example, you could insert a checkmark shape in an object's Visited state. Even better, you can add animations to those extra objects with a state. So, for example, that checkmark could fade or wipe into view.
