One of the cats will turn red and you have to click on it within a second or so to get a point. Then another cat will turn red at random. If you click on a cat as soon as it turns red the next one will turn red more quickly so you can score more points. You have 30 seconds.
Someone needed help with detecting a mouse click within a time interval and it gave me the idea for this game. It could be developed further but I may leave that to remixers. In the code I actually have two versions - one using clones and one using 'stamp'. I think 'stamp' could be used more by a lot of Scratchers. Whichever sprite is not in use just needs a 'hide' in a green flag script. If remixing you can choose which version to use. The stamp version is simpler but the clone version would allow things like having the cats dancing!
