Double-click the green flag. Press the Scratch heart. When you have 50 or more followers, press the red button. By the way, there are more than just stars. The highest message is "Awesome!" If only this was how followers really work. Then I could get lots of followers. But it's never gonna happen LOL.
Thanks to other clicker games and projects, apps and on Scratch, for inspiring me. And thanks to my Au Pair for testing the game.
