final hit on death adder was changed to death bringer because that is the correct name for the final boss.

Add column to pass without deaths

what do you mean? are you saying to add a category for a deathless run?

if so. the answer is no because the fact of the matter is that whether you die or not is already being measured in the runs. if you die, it is already calculated in the time because it causes the run to be slower. so making a category for a deathless run will still output the same results on the leader board. the only difference would be that there would be less players which would defeat the purpose of making the category in the first place.
