Quote from Chazney:
I just realised that I have been unlocking doors without thinking about it and that would be an item usage.
I disagree. On the other items (swords, daggers, grapple, smoke bombs...) you have to pick something up somewhere in the level, even if you automatically get it at the end of the level anyway. This is not true for unlocking - you can do it immediately on the first level (saving ninjas and Azai) without having picked anything up, making this an innate ability that the ninja has, not an item that is picked up.
