I agree with the werewolf being a bit lackluster. We tried to add two experiences for the werewolf. One that allowed you to transform at will to get out of trouble (he moves a lot faster) and a second to add invulnerability so you can beat on the bosses.
A thought I had was to allow the werewolf to move through enemies instead of colliding, thus making the "escape", just as the form was about to end, more tactical.
Thanks for playing and giving great feedback!
