Hi
I put all the hearts in place but the wall did not open. However, they are not in the same places I saw on a walkthru. I tried to move them to march walkthru but they will not move. Do they go in certain spots? If so, how do I move them? I can't finish the game until the wall opens, right?

Thanks for any help.
