Unlike most typing games, however, this game is notorious for having an insane difficulty curve. The game has a "Words per Minute" requirement for each level, being as low as 10 on level one and as high as 85 on the third. By level five, the requirement reaches over 500, effectively making it impossible to proceed any further. Another rather disturbing aspect of the game was the design of Mr. Mix himself. He was a large, round-faced, overweight man with large beady eyes and red spots on his cheeks. "I'm Mr. Mix. Shhh."
