Is there any replayability?

I played it on Shockwave since I a member and I could play it without buying it. But anyways, there are some things like in the attic, I saw a small house and when I click on it it said "You must find the part that goes with it" or something. But it was not one of the items that I could sell at the sale. It was not an item from the list of objects to find. So if you replay the game a second time will you get different objects to find or is it just the same things over and over?
