Strategy:
When you see the puppet's hands, click on it to flash the light or to close the curtain
----If you close the curtain or flashlight the actual puppet's head, you will die
----Puppet's hands, I believe, are both JJ and BB
----When you use the flashlight, click S to charge the battery (Icon shown on the bottom right of your screen (3 bars)) and to go back up press W
------Every single time you use the flashlight, consumes 1 bar
