The game does have a basic 'How to Wiki' built into the game, press the Escape key and one of the options will be How To Play.
It details out a lot of the mechanics, but there is no 'guide' as in go here, talk to this person, go there, do this thing, go here, take this skill. You are just thrown into the game and let loose to wander wherever you want.
I am not sure how useful it will be for you, but I made a map of most of the zone connections for the public version (0.4.02). If it helps, great, if it doesn't ... /shrug sorry, I scribbled it out on a post-it note and made a MS Paint image from that.

It is just a logical map, showing which zones connect to what. It doesn't show each zone or where each exit is physically, most of them don't need it though.
