Here's something that I'm stuck on:
I've completed all 50 puzzles and haven't got the achievement, and the achievement tracker indicates that I've only completed 35. The achievement description reads 'complete all 40 puzzles', which implies that the game may have originally been designed with 40 puzzles. This might be a developer issue or a site issue.
To be honest, I didn't think much of this game. I will admit that the unexpected plot turns and the overall artwork were good, yet I felt that the game itself was based upon misunderstanding.
The book that was the reference for this is called the book of Revelation, not revelations. In addition to that, the events described are from a period of time, which is actually close at hand, called the Great Tribulation. This period of time is explicitly described as the worst time in human history.
Along with that, the strange beings aren't literal beings. They are symbolic of something else. As a matter of fact, I saw a video that explain a theory that the locusts are actually helicopters, since the writer of Revelation lived almost 2000 years ago and would have had no idea how to describe modern machinery.
There are three things that I don't like about this game:
1: The book puzzle in part 1.
2: (most of all) The sliding puzzle in part 3.
3: The timed part 4.
