I didn't put a tutorial in game for a couple reasons.
1) It'd break continuity - I wanted to avoid this
2) It wouldn't work story wise - these people have been here for months, they know how to fight.
The Manual is in the game folder.
The Readme points you to it.
Here's a quote:
QuoteOpen the Manual.htm file in the Manual folder
it explains all the unique stuff you need to know.
if you don't read it, you may find yourself confused by some
aspects of this game.

I put it there to help explain things so that I didn't have to break the game continuity just to explain how the battle system works, or how to use set points interface. If I wanted to do that, I wouldn't have made a manual.
I provided you with the resource to learn what you needed to know, you just chose to avoid it.
That all being said, you can put up to 6 moves on a character, not infinite moves, if you press ESC it'll take you to the previous actor, if any, if you click "Set" it goes to the next, if you click "Revise" it deletes moves from the bottom of the list up.
