Mr.Mix（原文）

An artist rendition of their nightmare of Mr. Mix.Does anyone remember an old PC game from the early 1990s called "Mr. Mix''? It's mainly a typing game, similar to Mario Teaches Typing, where you have to type words into a box to make a chef (the titular Mr. Mix) put ingredients into a bowl.
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.
