What I found so fascinating about myself playing the game was that I started avoiding the other elements. At least those that were moving. If the elements looked like they were 'having fun' I wouldn't approach them because I did not want to interrupt their fun. But if the blocks weren't moving then I would try to approach them. Only to be rebuffed.
It had a real emotional effect on me. It made me, just a little, sad. So much meaning in such simple interactive elements. Beautiful work.
