Ok I had a lot more fun with this than anticipated, even though it took me longer than I want to admit to figure out the trail thing and how your health worked :D
But the combat mechanic and the letter thing was absolutely brilliant. Navigation and exploring was great, but I gave up at the wind section. I think that was too much for my brain, I just couldn't figure out where and how I needed to go to get out of that section. Think I was close to the end though, but that's fine.
I really, really enjoyed this entry. The only unpleasant bug I encountered was the audio files overlapping each other when you didn't wait for one clip to end and did actions that triggered another one to play.
