I still don’t seem to be able to draw arrows in any direction other than up. Luckily, you rarely need to (except perhaps at a slight angle), and on those few occasions when I have needed to, I’ve quickly rotated the DS. You might think of that as cheating. You might be right.
Anyway, Chapters 7, 8 and 9 were all felled. There was a boss at the end of one of them, which involved bouncing arrows off mirrors to hit him from behind. I’ve also mastered the Bomb Gesture. Which lets me draw bombs, obviously. I did have a bash at Chapter 10, but died.
I also noticed today that, on the level select screen, it says “Book I”. Which suggests that Chapter 12 isn’t actually the end of the game. Tch.
