Could Someone Help Me Find a Game?

There was this one game I played a long while 前 and I can't seem to find it. It's about a man and a fox. あなた control the 狐, フォックス and あなた find pages of a journal(?). あなた also look for mushrooms, I think. The 狐, フォックス can also find keys and unlock things, I believe. Plus あなた can find 妖精 (some strange light) that surround the fox. There's also some strange temples - I think - that gives the 狐, フォックス some strange "boost" of some kind. Does anyone know of this game and what the タイトル is?
