Press the green flag then tap one of the cats to see if it is the right one! Keep guessing until you get the right one. Then, you can try and keep track of the right cat the next time and press the green flag for them to move again. Tell me in the comments how many cats you pressed on the first round until you got the right one. Hope you enjoy... ;)
Thank you @Sam-Min-Kat for giving me the idea without knowing he did!
