This challenge is barely related to a Waltz, only 100% guessing and slamming ciphers together. The hints also weren’t that great… it only threw me off thinking about the beats in a Waltz (which is somewhat related) and the “step side close” for hours (which is useless). I even started drawing diagrams trying to find some square pattern following the footsteps of a Waltz.
This is definitely the worst CTF challenge I have ever seen. I am not sure what the person who approved this challenge was thinking… if that person was thinking at all at that moment.
As @sampriti said, please rate this a piece of cake and give it a thumbs down. It is a complete waste of time. Sorry @0xEA31 , I really enjoyed the CTF and Lightweight box (and learned a lot from them!), but this challenge really disappointed me.
