first off, make homer always guard the left. this blocks barto and millhouse, which is super lucky since new homer comes at about the same time as millhouse.

keep your mouse moving. dark homero is the biggest threat of the max power mode, so make sure to avoid him.

shadow marge/forgot her name

make sure to always point the light at that section of the office when turning back, or your office may get dark.

old marje: the good/bad.

marje will come to your front, some people say 33 %

that's a lie though, it'll only stun her for a while.

use 50 % just to be sure.

make sure that in times where you have no light, new lisa is always there.
if you are at..5:50 and dark homero destroys your light when it's at full power?

be a badass and ration your flashlight uses.
