I would like to suggest an additional game, a speed test. It could have a toggle switch to allow a choice between the fuzzy typing and exact keystrokes, and the scoring could include not only the % correct, but also a words-per-minute score. That way, folks practicing typing could use their own texts. The speed score would also give non-typing users an idea of their confidence in completing a passage. A second-but-complimentary feature would be a chart to track progress over time.
