This is an interesting way to help you get your typing on the iPhone down. However if there are too many letters/words/numbers on the screen the game really slows down and it makes it difficult to type anything precisely and quickly. Fix this and it will make this a lot more enjoyable. Also, it would be cool to try the game in landscape mode, and maybe switch up the visual perspective when this happens too, just a thought.
