Kobo II Tech Preview 2 file

Mostly internals this time, though there is now "all-to-all" physics going on (that turned out to be quite a bit of work), and background collisions have been enabled. The enemies are not yet particularly skilled at navigating through the terrain, but at least they're trying to not just crash into the first wall they find. Oh, and something weird has happened to the title screen starfield. :-)
