While I like the concept of the game, it becomes rather stale after a few seconds.
Here are some improvements you should think about:
1) Decreasing the size of the board, its a bit to large right now
2) Offering help if you get stuck
3) Add power ups of some type
4) Add additional levels
5) Music is decent and generic, but could use more, maybe different versions of different songs.
Over all pretty good and has a lot of potential, love to see a second edition.
