I know I'm majorly late to the party, but:
A) This game is fantastic.
B) I am very much stuck on the last (?) puzzle. It's the room with 2 boulders, 2 statues, and a platform that goes all the way around a central island if you let it. I can't even get far enough to prove if my 'solutions' will work or not. I put my faith now in the power of posting.
