This was absolutely fantastic!
The art was stunning, the soundtrack was superb, and I had a lot of fun just standing in the last level shaking my staff at the collector XD
I know a lot of people in the comments are saying that the logic of these puzzles is hard to understand, but I'm really not sure how you could make the mechanics any clearer. The little star in the corner of each star indicates the way in which the stars want to line up in relation to one another, and by moving various stars up and down you can affect this relationship. The line that showed up while you were moving them was very useful, and the wobbly line to show that you were going to change that star's orientation was a nice touch.
10 out of 10!
