The let's plays of Rktcr continue to accrue. The general consensus seems to be "this seems intriguing, but is awkward to pick up and play." I take this as an indication that there aren't really enough challenges that are possible at the low end of the difficulty curve.
Suggestions for easing this initial portion of the difficulty curve are welcome, of course.
These are the let's plays of which I am aware. I will add more as I learn of them. (Comments and e-mail are both welcome.)
