You are the blue circle, the blue circle will go where your mouse is. Try to touch green circles, they give you a point. Try not to hit red circles, they take away two points. If you get twenty points you win, if you get negative twenty points you lose. If you can not win stay alive as long as possible. Press the play again button to play again.
Thanks to the book Coding Games In Scratch for the base code. The play again screen was made by me with help from CHEESYCHEESEBURGER9. Enjoy! :)
