Not bad, but the horse-riding? Just repetition, because there was another obstacle you didn't see because of a tree moving by, or because the controls don't react that nice or whatever. Sorry - too annoying. Couldn't continue.
Too random - this could be a good game, but the combat is just plain annoying. I can't shake the feeling that the PC gets the better rolls, and with the way the combat is handled, this means lot of frustration - poison for any game.
