Just a short review to add my voice to the others recommending this game.
Despite a very "indie" feel (black and white art, unremarkable formatting, etc) this is a brilliant book, dripping with thematic pleasures, and evocative of a mood that other games have often attempted to capture, and fail.
The rules are simple, but mechanically pleasing, and the setting and cosmology is just breathtaking. Even if you don't like one of the worlds suggested, it's very easy to swap it out for one of your own creation, and the themes are laid bare enough that it's easy to keep everything in line, without being intrusive.
There are some stunning narrative touches which make the game a joy - the obsession with the number 13, the broken clock motif, and the five stages of grief to name just a few.
It's truly an excellent game - bought on an impulse and well worth it. Would highly recommend.
