Oh another thing- I enjoyed the random text display, but it went entirely too fast to catch one message before it would get changed again to the next. This in itself was another interesting experiment (I presume) and while it gives a little bit of replay motivation to catch the ones that go by, I find it leans more toward annoying/frustrating that I'm missing the messages. I think the experiment shows other existing reward systems (such as a simple 5/5 boxes destroyed to next message) are superior in terms of motivating the player presuming the messages/rewards are interesting.
