Instructions on navigating the linked Unity "Digital Worlds"

• Use the arrow keys on the keyboard (or the w, a, s, d keys) to move around.
• Hold the shift key to run or the space bar to jump.
• if the keys do not seem to work, click the mouse directly in the area of the "Digital World".
  It should then work.
  
• Each of these "Digital Worlds" has 3 interactive "hotspots", but they are not always obvious
  ... You'll sometimes need to explore to find them all.
• It may take a minute or two to download Project 2 and 3.
  They were not designed as web apps. Please be patient.
