Mission frustrations

Great game overall, but I have some frustrations with the second round of missions.
First, some of the missions arent labeled as "in one run," but bed up resetting once you die.
Second, the mission to not attack an enemy with Kunoichi for 500m is near impossible if it resets every time you accidentally attack someone when youre in the air or trying to avoid obstacles.
Third, how are you supposed to die by a samurai two times in the sane run?!?
