When my fingers hurt after too much time on the keyboard, I... Well? My fingers do not hurt. The mouse hand sometimes gets cramped up but that is about all. But typing the game helps with the cramped hand of the mouse. I love the game. I am seeing improvement already. To me it is just a way to improve myself and to do better at the typing skills and to know that if I had a better spelling ability I would do much better. How ever, I only read a normal speed of 80 wpm so to type 20 to 30 words pm is really good for me. I also find that my reading and attention skills also have increased as well. I find that when I think I am slowing down or relaxing more that is when I seem to type more words per minute and more accurately. Needless to say I am pushing myself and then relaxing a little more. I also find that I know where some keys are but need to learn of more.
