You overflowed my buffer, now get a shell. The flag is located in another_flag.txt. Connect with nc oreos.ctfchallenge.ga 7331. Good luck! (The binary and connection are the same as in the previous challenge, called "&aaa")

Introducing ICICLE (Imaginary Ctf Instruction Collection for Learning assEmbly)! It's a programming challenge, so I didn't want to use an existing language and give some people an unfair advantage, so I made my own! See the spec and implement an interpreter to run the provided file, and get the flag.

The Green Shell is a launchable, which when launched from a player, will start moving. The shell takes 5 bounces on walls before it will break. This can be deadly to players ahead as they must dodge it. It is referred to players as the "worst" shell, mainly because it roams freely instead of targeting a player. The shell is green with black lines. Connect with nc oreos.imaginary.ml 12345.
