People overcomplicate the fight. When you look at it for what it is, it's extreme FNAF. There are a bunch of batteries that power different things in the room. One powers the doors directly to your left and right, one powers the Green Hand terminal, one makes it brighter, and one doesn't have a use. Catnap will come down those 4 hallways, but fakes of him will also come down the hallways. To make sure you don't waste time with them, use the Flare Hand to see if they are the real one. If they disappear, they were a fake. If they do not, you need to block the path. If he comes down the front right hall, open that gate and use the green hand to power the thingy. If it was the real one, you will hear a scream. If he comes down the front left, be fast. Use the purple hand to jump up the wall, and use the green hand to activate the thingy CLOSEST to the hall. He rarely does it, but if he comes down the hallways to your left and right, move a battery to that hall. If he comes through the vents, simply close it. You will need to insert new batteries every once in a while, removing your options. Do not try to go into the hallways. Do not try to block the path whenever you see a Catnap without checking. Do not let him catch you.
