I'm a relatively slow typer but I still survived about 7 rounds on easy at least (which I found to still be quite stressful), and I found it interesting. I really liked the visuals and atmosphere.
One thing I found a bit frustrating was that if there's just one letter off it's no different from being completely wrong. Perhaps it would be good to have some way of comparing on a per-letter basis so that just being one letter off (including either missing or adding extra letters) doesn't give as harsh a failure as being more off.
Another thing I would note is that in terms of the overall score, the 100% bonus always felt way more important that the time or accuracy values, since even if you're late it still gives you 100 points.
