osu! (iPhone OS port) - Kumo no Iseki (hard) - Using AA Battery!

So uh, I read this article lifehacker.com/... on lifehacker and had this amazing idea of playing osu with battery. It's better than finger in some ways but the usefulness is basically questionable.
It's a casual (translation: terrible) so don't expect awesomeness or anything!
By the way, I'd recommend you don't try this on your own device.
Also, I hate vocaloid.
