Drag the cat then press the green flag to make a stamp and move. You don't need to press that red stop sign. to clear go inside and back to the project page to start over. I keeps track of the how many times stamped world wide. If some lousy user messes it up, let my know so I can fix it. So, each time you stamp, everyone knows someone did it. The arrow shows the real cat.
All credit to me.
