You're welcome, Solver.
By the way, I just checked the walkthrough at the Alida
site, and the directions are there. I just think it's so packed with information that it's easy to overlook small details.
When I first played, it took me a while to realize I could go up another level. Something that happened with an elevator in Myst
surfaced in my gray matter, and I had a mini "aha" moment and pushed the button again.
