I'm a pretty good typist looking for an "in" for rhythm games but after playing for a bit I get the feeling this is a game for pretty good rhythm game players looking to learn to touch type. Whoops.

The tunes aren't really there either. Also, I'm not sure this would work all that well as a typing teacher, since so much of getting good at typing is learning to group things and typing words as single motions rather than individual letters, and this is just asking you to peck at contextless characters one at a time.
