I'm not sure if it will be needed. it's a good idea, though it will probably feel too similar to the normal 100% NPU. I don't mind if it is added, though I'm not too interested in it
100% Glitchless (and any% glitchless) will probably be more important to have then true 100% in my opinion.
Also perhaps a no-skips any% category? (You have to go through the game without skipping powerups you "need" or using other skips like AA skip)
