The cat moves with your mouse the up arow makes the cat bigger. The down arow makes the cat smaller. Right arow makes the ghost effect stronger. The left arow makes the ghost effect smaller. The f key makes the fisheye stronger. The d key makes the fisheye smaller. 1 makes the whirl effect stronger. 2 makes the whirl effect smaller and space key clears all.
I got the idea form a book called "coding projects in Scratch."
