Move the robot around the screen to reveal a hidden letter. But wait! There's a bug in the code. The robot should move in 4 directions using the arrow keys, but one of the keys doesn't work as expected. Fix the code first so that you can move the robot in all directions. Once you have revealed the letter, add it to the url cmp.ac/ and navigate to that page to find the next clue (and add the letters to the ones you found in puzzle 1.)
