What an atmosphere! I loved the music, the theme, and how your actions tie into what you see in the gallery through the visitors and the newspaper—all wonderful touches.
Towards a minute or two into the game, I found myself just scaling down the fragments to their smallest 1:1 size and then slowly scaling the Y axis until it placed the fragments for me. It kind of trivialized the gamey aspect.
I think taking the puzzle aspect further by making you place the pieces as well as to scale them would have done wonders to de-trivializing the scaling problem.
Overall I had a wonderful and relaxed time throughout the 3 rooms i've played!
