Beautifully heartbreaking. Amazing take on the theme, like others have said the looping really adds to the feeling of total monotonous apathy.
Great art, great music, great everything really. Except the controls, it was a bit tough for me to remember which arrow key did what. I haven't really played anything with a similar control scheme. I'd probably gravitate to Arrow Keys + Z and X.
All in all though like I said, I love this game.
