What an enjoyable game! My heart was racing in chapter 12. This is a quite long game set in a world dominated by clockwork; the religion, the city, the people's mindset, everything is based on clockwork (a funny moment was seeing that pagans worshipped non-mechanical timekeeping devices like water clocks or sundials).
You play an assistant clock keeper who must investigate a future robbery. The game is a very long example of what I call the linear thriller type of game. You encounter a more or less linear sequence of challenges where you are given a good amount of hints on what to do, there is always a sense of urgency, and everything you do is the right thing in just the nick of time.
This game is what I wish the illustrated book Hugo had been from its cover; you jump and leap and fall all through a giant clock early on, you use an early calculating machine like a computer, etc.
The writing is as good as Anchorhead, in my mind, and the implementation is smooth. The story wasn't as compelling to me at first, but the last few chapters really got me into it.
The game has probably not received very much attention because it was a commercial game for a while. But everyone should try it now.
