I should say something about ch5-328 by Iron.
It involves a very hidden trick(bug) that new players may probably not know.
Suyono first discovered it and he referred it on Yahoo Group. It is called "quiz 08". Years ago I was trapped by the quiz and Secret Squirrel tell me the secret.
And the trick occured again.
You are welcome to ask me if you need.
By the way I beg your attention to "999".He is a talent hardcore player and he has solved scores of deadly levels.We cooperated to solve ch5-328, and he by himself found a shortcut of ch3-3 very fast�Rwhich once trapped me for years.
