Not bad
A good time waster and also a good way to build typing skills. Could ask for more variety, but the basis of this game is repetition. I certainly can't think of anything right now, but perhaps you can find a way to incorporate different modes of play? Maybe different difficulty levels? Oh and by the way the numbers definitely set me off and were tougher to get in the time alloted, which was different, but annoying. All over, though, good job.
