Use the score variable to change the number or click the cat. The auto clicker will gain the SCORE variable and subtract the SCORE variable when it's the maximum! Update: The cat changes the color and maked the auto clicker's shadow on it! When the score hits more than 999999 (Which is the maximum score can create), it automaticly set the score back to the maximum!
The number has 6 digits if its the most number. "999999" If you try to make the screen refreshing to check if there's a problem with a maximum, Scratch will be lag so becareful or the Scratch page will make a mistake when you refresh the page (Mistake: Deleting your Scratch account)! Thanks @griffpatch!
