Sorry for the double post, but I've added 4 new images showing more of the debugging text that can appear. They are currently 4 of the last 5 images on this page.

Still no access to the debug menu itself, but Ill be digging out a USB keyboard adapter at some point to test out that theory.
More importantly though, I've added an image showing that there is, at least, rudimentary multi-player support. I say multi-player and not multiplayer because I haven't found evidence yet of any actual multiplayer mode (although I have my hunches), and functionality is limited to the second controller controlling the character. But I still think it is fairly interesting!
