I love Luigi's Mansion but on the old clockworks boss mission I got very frustrated. I can't get past this because they don't give you enough health to survive everything. I have gotten to the 12 o'clock battle multiple times and have gotten beat because they don't give health throughout it. How are you supposed to fight 4 ghosts, one of the them with almost no way to see them so they sneak up on you, and fight the boss if you only have 60 health to start? I was fighting the boss at the end of the 12 o'clock battles with only 5 health. How am I supposed to survive something that crashes intro walls before you can blast him with only 5 health?
