Nice. I'm anxious to see what it can do. Though, I'm using a pretty badly outdated computer, and I can't even begin to describe how slow it can be sometimes, so I'll likely have to pick up a new gaming card.
I know what it's like being stuck on this game, as I've found myself in that position a few times, though I've always managed to find the way out, until this part. Hell, that "Round and Round" puzzle should have been the first puzzle I figured out, but I didn't solve it for a while, because I thought "Well, it DOES say "Round and Round", so you probably have to... nah, that would be TOO obvious." But of course that's what it was. 
Reading some of the earlier posts here, I'm surprised so many people missed the Copper Key. That was the second thing I ever found in this game.
