HELL NO, Do you know how many deaths stages 7 & 8 cause me in episodes 1 and 2? I prefer that casual mode stays as it is because I don't intend to repeat the entire episode from the start; it's hell.
Another thing: I had defeated 9 in episode 2 and pressed save and exit, but instead of saving my progress after I defeated 9, THERE WAS NOTHING. It was a nightmare...
