Just move your mouse pointer towards where you want it go, but you have to move it slowly because you have to avoid the purple and black rectangles and the ghost, so you can reach the flag.
I would like to thank Scratch website, for letting me use the background, characters, code, and other things. I would also like to thank Coda kid, its teachers, and helpers, for guiding me this far. Without learning how to code in this website, I couldn't have done this game. So thank you to coda kid, and Scratch, and this user of Scratch, for guiding me this far.
