Majestic Update:
To be honest. I'm still not real sure about this game. It's kind of interesting. But the story is (as far as I can tell). Mostly just on rails. You can only do things as they give information to you and there isn't any real branching that I've been able to tell. So it comes down to did you happen to figure out the needed clue to get to the next step. It isn't even like there are multiple ways to get there (that I can determine).
It's definitely a very interesting concept though. I could see this kind of game really getting quite complex. I'd love to have there be little side puzzles you can stumble across that are part of the overall storyline, but if you miss them you aren't missing anything.
One of the funkier things is getting IMs from the game. I personally think that is pretty cool. They do need to work on the parsing of stuff a tiny bit, but it isn't too bad for a start.
