I absolutely love the fact that this game has no instructions and no scoring. It is blindingly simple and very addictive. Really smooth animation here enhances the gameplay. I won't give too much away as you will learn more by playing it. You'll only need about 3 minutes to fully absorb the game and you won't need to go back for more so don't worry about getting addicted. This is great use of how to pull users into your site and keep them there. You could use this as a pre-loader if the file size is small enough.
