In any Zelda game where link could do a spin attack, if an enemy hit him while he was charging, the charge would be interrupted and Link would have to try again. In ZC, when link is charging for a spin attack, and gets hit by an enemy, he continues charging but when the spin is unleashed, it fails to make contact. Also for the Hurricane spin (even if link is spinning and somehow gets hit, the rest of the spins fail to make contact).
Finally, if you get hit while charging, fail to release. and get hit again, the charge is interrupted, and link will only face the direction he was facing while charging and cannot use items or his sword until he leaves the room.
