Just click the green flag then hit the start button. You will have to press the arrow keys when the sprites pop up to control the virtual cursor in the animation. NOTE: This is a prototype. In the future, I will unshare this to work on it some more, add some more choices and hundreds of new frames, then reshare it again. Stay tuned!
