Fantastic game!
A couple of things to note.
It should be "Again", not "Agian" on the final button.
And if you're going to have a looping song in the background, I would make it slightly longer. Nevertheless, I enjoyed the background music, though found myself bored of it pretty quickly.
It was very enjoyable to play. A new twist on a classic tile puzzle. 4/5, 8/10.
