I wish Zun would change the difficulty settings on his games. He should get rid of easy, normal and hard.
A better system would be as follows.
Lunatic 1: Regular lunatic
Lunatic 2: No continues
Lunatic 3: One life only
Lunatic 4: Lunatic 3 but bombs are turned off
Also, there should be an extra stage where you fight Orin and Clownpiece at the same time. Because fuck you, that's why.
