I bought this on Steam since it was 80% off ($1!), but there's no manual included, and the in-game is a bit short of some key information, like, what do all the skills do, and how does one use them?

TLDR: Does the GOG version come with the manual? And does the manual actually contain anything of use?

From the 'goodies' list it appears it does, but I want to see if anyone can confirm that, since I'm basically at the cap to be able to return it to Steam. I can see there are some files on random sites for download, but...I'd prefer to avoid that sort of risk.

thanks!
