Click the Green Flag to Start Move the cat by moving your mouse. When the cat touches a yellow sprite, you get 10 points. If the cat touched a pink sprite, you lose 10 points. The highest possible score is 200.
I got the idea for this sample from a resource by Karen Brennan on ScratchEd http://scratched.gse.harvard.edu/resources/lets-play In this version, I used clones and then randomized their locations. If a yellow clone appears and is touching a pink clone, then the yellow clone moves a little.
