Manual for demo?

[Michaelangelo]

I've tried the tutorial, it explains 'how' to play the game (mostly), but there isn't much to explain the factors that go into the game. The descriptions and unit stats explain some, but there seems to be a lot missing. It's hard to tell what many spells do, nothing to explain what certain effects mean and do and how they affect the game parameters, etc. Is that the kind of detail the manual provides, or is everything hidden behind the game engine?
