TJCTF - gravitymud

This problem solve to have sense, It is MISChallenge

we use north,south,up,down,east,west,examine ???.. 

Then, Let's solve this problem

This Binary has map, The game is to imagine a RPG Game

It is RPG MAP 

Hey you, Note Make a map!

아 영어 못해먹겠다

각 맵에대한 가젯이 존재하는데, 각각의 맵에 아이템이 떨어져있는것을 확인하고 examine 명령으로 아이템이름을 인자로주고 명령을 넣어주면된다.

하지만 그냥 주는것이아닌 등불이 필요할때도있고 히든맵이 존재하며, 어디를 들러야 되는곳도있다.
