Anyone else been using this app? When I play the mode where its a black screen and when you touch the screen little dots of light appear, it feels so futuristic, like this will be what musical instruments will be like in 100 years. I also love how you can play pre-made songs on it almost like you are actually playing them, but not quite. Its sort of like a sleek, minimalist guitar hero, but for piano. I'm surprised they are only charging 99 cents, it seems alot better than some of the games that are charging 10 bucks.
