How do you get the key on Gretel and Hansel?

when u first start shoot the clock and grab it, afterwards when u get outside go to the well (far right) and stomp or shoot the butterfly, pick up the clock arm that the butterfly had. go back to the room and shoot hansel until he dies (yes that's how u get it) when u are back in the room u will see that he dropped a clock arm. get it.

go to the clock in ur inventory and make the big hand on the 6 and the little hand on the 4. get the key go to ur room and go up to door and click and hold key to door.
