Click anywhere on the screen, watch what happens.
"Create a project where a user gets a surprise every time they click on the screen." I wanted to have a surprise character clone at the screen position of the mouse click. It worked out as planned except I have a problem where unexpected costumes are used if the user clicks the mouse before the previous actions have completed. I think it could be solved with a strategic wait command, but no more time today for troubleshooting. I'm happy with it.
