to GameBoomers, Lion_1251 (Dick). Thank you so much for posting and introducing yourself so that we can get acquainted.
As I have said before, I truly admire and appreciate walkthrough writers - it involves a lot of work and intelligence. Most of our members here prefer written walkthroughs over video walkthroughs, and I agree completely that it's often difficult to discern the how and why of a puzzle solution while watching a video.
And a note to Louis: I have always seen walkthrough as one word, without a hyphen.
