That being said, let me help you get ahead of this game by giving you this guide laid out below.
In the first scene with two skeletons, pick up five items: one on th floor near the left skeleton, the chains tied into the hands of the left skeleton, the empty bottle, skull and bone. from the right skeleton, and the rope from the skeleton facing the ground. Use the first item to lock pick the keyhole on the door.
After that it would take me very long writing it so I will just demonstrate House of Fear Escape walkthrough via the video below.
