On the first point, the game's randomness is biased towards easier languages earlier, and harder languages later. But I didn't want to bring with me a preconceived notion of what languages people would find hard. If you were to track your maximum score, you'd probably find it trend upwards as you trained. So scores are still useful in that regard. On the second point -- I completely agree. Validating the samples takes time, but I promise I'll add more as soon as I can. Thanks for playing :)
