I'm pretty sure this only applies to hero mode. The thing is imo, as fun as it is (i've done it casually before), it's hard to keep track of. It's very easy to touch enemy ink for a single frame, but there can and will be moments where you accidentally touch ink and not even realize it. Plus, this would be a moderating nightmare, requiring a full review of the entire video to make sure it's not cheated.

A rom that instantly splats the player similar to OE would be nice, but from what I remember, OE stuff can't be implemented into HM unless I'm mistaken. Would be cool tho.
