Original instructions: Just move the mouse around. This will always point towards the middle of the screen. If you like this: https://scratch.mit.edu/discuss/topic/123032/ Also, check this one out, cuz it's better. https://scratch.mit.edu/projects/87161928/
Things I changed: Added a starfish that moves randomly. Made the arrow track the starfish, so it isn't just pointing toward the middle. Made the arrow red for improved visibility.
