Good idea, but a random order / randomly selected words from your dictionary would be much better. This way it becomes very boring. I have no problem with writing the words, but it's much to hard to press Enter at the right moment and for enough time.
Checked, there seems to be a bug, when you die words rest to wrong ones, so sometimes you end up with big word where it was a small gap... Or was it on purpose?
