ap is adventure points, and if they run out and you move, it does damage. thats what potions are for ^^. BTW, the music is pretty awesome. luv it!!!!!!
i think one thing they should have looked over is, if u are new to this game, it shows u how to play, but it's so long that a lot of people get annoyed, and skip it. thats what i did,and when i played, i understood it at first, untill my health started to drop for every movement, and after a while, i found out what ap did if it ran out, so now ti's really fun, and it is enjoyable if u know how to play it.10/5 lol
