Somewhat unique
I've noticed the game having problems keeping up with typing being too fast, missing characters which breaks your stride and makes the game impossible to complete.
also showing punctuation that does not need to be typed also messes with the rhythm, slowing down the player as well.
Overall it's a unique idea but not exactly executed well enough or interestingly enough to be called a game.
I will give you credit for trying something a little different and hopefully you hit on something new that is fun to play in the future.
