Q: The Scratch Cat should do a flip when the space key is pressed. But when the space key is pressed, nothing happens! How do we fix the program? A: Add delay times ( preferably 0.1 seconds ) in between each [ turn ↻ (90) degrees ] block, and add one [ wait (1) seconds ] after the final [ turn ↻ (90) degrees ] block for when the viewer holds down the space key. Easy as that!
