I thought it was OK. I like it when gameplay employs the use of different forms to give you new ways to play, the transformations are one of the reasons I love Majora's Mask so much. But the wolf form didn't live up to MM. In MM each form closed off certain possibilities, but yet provided whole new possibilities and abilities you couldn't access in other forms. But the wolf form didn't provide as much as the basic human form, it simply closed off too many things, but did not provide enough of its own things to compensate.
It definitely was fun though. It is kind of neat running around Hyrule as a wolf.
Well, I don't mean to be critical of such small things but for me Wolf Link was amazing, easy to handle and well structured in the game's surroundings. The only thing it could've done without was Midna sitting on my back. Sometimes I didn't feel as if I had become a wolf with Midna riding bareback.
Wolf Link was amazing during Twilight Princess. Only a few things could have been tweaked better for the game to be close to perfection. One of these objects, is obviously the collecting of the tears in major regions. Maybe if Nintendo could have given him more features as a wolf, such as maybe calling out for friends for aid (if it was possible), then maybe the tasks of collecting of tears wouldn't be so tedious, boring, and juet down right tiring to complete.
