Hack the Code Rocket!

No in-depth explanations to be found here! This is a fun program that uses all of the code concepts you saw in the projects, plus more! If you’re up to the challenge, dive into this program and try to decode what it does and how it works, using just the code itself and the comments throughout. Enjoy!
