Its a mission, I really want to like; but has a great many flaws I can't overlook.
Mega-Giant Architecture; for 3 Meter tall people. (everywhere, not just the giant sized mansion!)
Out-of-Order objective completion (not a flaw; just mabey missing scripting?), before its issued!
A little TOO much back-tracking (all those objectives, and optional ones)
There are good parts to it; its still certainly playable - and has unique pagan theme that IIRC hasn't been done anywhere else. I can't really fault having piles of readables - just any time a illegible handwriting font is used!
(especially for objective related stuff!)
Perhaps it could have been re-worked into 2 or 3 smaller maps, once a section is 'complete'?
Good ideas, I haven't seen done elsewhere:
3D map with paths (mabey use a grayscale filter on it next time? for a more hand-painted look...YMMV)
The whole
Interesting distractions, implemented imperfectly; but still worth a look...
Revisiting old areas...
In short my rating: Play it if you've played everything else, its OK.
