Could Someone Help Me Find a Game?

There was this one game I played a long while ago and I can't seem to find it. It's about a man and a fox. You control the fox and you find pages of a journal(?). You also look for mushrooms, I think. The fox can also find keys and unlock things, I believe. Plus you can find fairies (some strange light) that surround the fox. There's also some strange temples - I think - that gives the fox some strange "boost" of some kind. Does anyone know of this game and what the title is?
