Just released an update for Endarchy, which tweaks a heap of stuff and changed some of the game play. The "hard" skill level should be a little harder to finish and both skills have some major game play changes at a few points.
The download has been uploaded here, but is currently waiting for authorisation - may be a day or two. If you can not wait that long, grab Endarchy (v1.0.1) from the main Endarchy site - Endarchy.com
I'm pretty sure this is the absolute final release :]
