Very nice work
Very addiciting an nicely put together.
While playing I came up with the idea that this game should actually be sold to schools. This is an excellent and fun way to memorize you keyboard. I'm already used to it, but children or even adults who are trying to learn where everything is on the keyboard could find this very useful. For a change you'd finaly be learning in a fun way, even if it's just memorizing your keyboard.
Great job!
