Dietrich Ayala added click and drag functionality to the project, via the Click Drag component, so after merging and pulling his changes to my local project folder, I installed it via:
npm install aframe-click-drag-component --save
I also edited my demonstration page for the project to make it much clearer which pages should be used for user testing in India next week.
Finally, I moved the virtual mountain a bit higher in the virtual sky to encourage users to look up.
