Solid typing game, having a rating system is a good use of the theme, but there are more areas where it could have been implemented. As a side note, rating systems are more engaging when they are visible during gameplay. Having the letter rank visibly update as the player types would make the game more exciting. Another interpretation of "slick" is minimal downtime. The theme could have been incorporated in the overworld with a fast, slick movement system. The typing system itself is perfectly implemented; being able to immediately write the next word and to write them in any order, is very slick. I had fun!
