0. Congrats on shipping.<p>1. This is really cool. Also scary. I think I might be the target market for this, I've long known that communication is my greatest professional weakness at this point, and within that, brevity is something I gotta learn.<p>2. I did one of the games (CVS, pharmacy, chemistry) and it was terrifying! By which I mean "I think I might be exactly the sort of person who needs to be FORCED to do this, and I did so, and it was DIFFICULT AND UNCOMFORTABLE", which means your thing works. :D<p>3. I had to copy the original text to a side buffer so I could refer to it while I was writing. It would have been better if I could see it, and the required words, on one part of the screen (left? top?) while I entered my new text somewhere else.<p>4. The timer didn't seem to work for me (firefox, linux), but that's fine, there's no way I could have gotten it done in time, and seeing the numbers decrease would have made it even harder. ^_^;;<p>5. I understand that "grading" in any sense is hard (you need a human), so I appreciate offering the example "correct" response, but you know what would have been even better? several "valid" rewrites, and perhaps a few that aren't! What I mean to say is, as an admittedly poor writer, seeing both an example of what to do and what not to do could be of use.<p>6. I wish there were a way to spend 1/20th as much for 1/50th of the paid product first, before committing to buy the whole thing. There's a large psychological difference between $5 and $100 and I'd pay $5 right now to test out the paid version 10 times, even though I'll probably pay $100 for it, later. I might not though! I might forget! But that made my brain hurt so hard I'd drop $5 without a thought.<p>7. A difficulty level for each game would be FANTASTIC! Can you do that? Perhaps just 3 levels. That way people like me who are looking to take their writing ability from "completely horrible" to "acceptable" can have an easier time.
