Press the green flag to start the game, use the button "W" to move, hover your cursor to a desired place around your screen to move and rotate the chicken over the balls. I didn't add a code to actually restart the project whenever the chicken got it by the ball ill fix it in a few hours.
When I was playing scratch, I was going to make another boss fight and then I asked my mate @FredGCoding15 to help with my boss fight project, he did tons of coding for me and thanks to him, for the balls I added a small basketball on the left of the project if you wonder why the basket balls aren't going for the chicken.
