Haha, perhaps I'm just bad at the game, but I was about to suggest it is a little too hard- let me give it a few more tries to see if something clicks! :P

-EDIT-
Ah, yes, you can press down arrow to start from below. Quite useful for the close ones!
Very good! Great little game, and I now understand Swoopie's critique. That being said, this is terrific and you should feel very proud!
