NOTE: Right now this code only works when you open it in the Scratch software (not in presentation mode or online). I am experimenting with answer/responses in a text box, and what we would need in Scratch to make this easier. 1) text boxes that you can write in during operation 2) check for a member (subset) of a list; 3) Get rid of Enter as shortcut for Green flag; 4) Type strings into math comparison blocks; 5) Maybe type into a variable on the stage (but maybe option to lock for presentation mode).
