I enjoyed the reverse engineering part that took me all of 2 minutes (it is meant to be very easy ofc)
I didn’t enjoy spending like 2 hours, even enlisting the help of a friend, trying to figure out the flag format :S if you’re into puzzles in general you’ll like it but I didn’t learn anything related to cyber security from that part.
my hint: look at what you’ve figured out, and then look at how the snake’s chains are created. Don’t assume the code is complete or works!
