I have to say, when this version was announced I thought it was just a cool addition to the main story, a side quest-like game. I finished it yesterday and damn, it was really, really good, I think this should be a must-play for everyone playing Rejuvenation and honestly, I think I enjoyed it even more than the main story; there were a couple of bugs (which have already been posted) but nothing that can't be fixed by the developers.
I had to come and make my first comment to give my compliments to everyone who worked on this game; yeah, that's how much I liked it.
