LOL, you didnt understand that frost? here it is:
if your name is luigie and you say left you go right but if you say right you go right anyways. Then if you say give key you actually appear in the top but if you say give key 1 then you exit. If someone says give key and there not luigie then it takes them left but if they say give key 1 it takes them right. Its really quite simple.
