So many complaints that it's not hard enough, and my complaint is the opposite, yet, ironically the same: It's not useful over a wide-enough range of skill levels. I was hoping it would be a good trainer for my kids, but it starts off too fast. I tried typing at about 5 wpm, and the result is a game that ends after just a few seconds of practice. If they don't start off already good, it won't give them enough practice to get good. They'll get bored with a game that won't continue for more than a few seconds in...maybe a minute.
