Open the Week 2 Student Hyperdoc provided by your teacher.
Open the project under the "You Do" section in your hyperdoc.
Play the project.
Fix the code so that the spaceship correctly says what layer it's touching.
DO MORE
Add more code to say "Wrong way!" when the spaceship goes off the layers.
Make sure you have shared your project with your teacher using your hyperdoc.
File -> Save to your computer to save your program for later.
