Well, I never cheated, in this wonderful game. but maybe it's because I have years of training behind and know the levels by memory...god knows how many times I played it. Huh, Unknown Hero, when the ghost jumps in front of you, u must IMMEDIATLY put away your sword and RUN through the ghost ( he actually is your image, so when you put away the sword, he'll also do it ).
My actual record should be around 30 minutes...without cheating.
Hope H.Hero will find this tip helpful
