Good but...
It starts as a great game, and there's lots of work on it, but at a certain point you get tired. Doing the same thing over and over again is boring, specially when you're improving a concrete skill: books, books, books, sleep, books, books, books, sleep...
Anyway, I got hanged to it. Good work!
