You click on the sprite that pops up out of the rock. Once you click on them, you get points. Try to get as many points as you can. There is time limit, but I didn't put how much time you have. You just eventually stop when this guy pops out of nowhere and says "Wow! you scored... "blank" points!". This game is very simple.
I had the help of my coding teacher from codeninjas. Just want to say thank you.
