I did not, but a cool feature that people won't use is an even more cool feature.
I think I'm simply going to describe most features :) but what I liked is solving puzzles using various spells (real spells like magic wands), and that there are clearly some cool puzzle sequences (the entire truffle thing, for example). I liked the big inventory which eventually contains many items at the same time. I liked that a real part of the world is available from the start and that the world opens as you play (no self-contained chapters). I've not looked in depth, of course, but it never seemed to me that I had to solve one puzzle after another and I felt that the order was quite open. The flexibility with allocating stats and spending your gold is cool, and the multiple ways to solve some puzzles and defeat some enemies is certainly the mark of a refined game.
