Horizon of Darkness

In the general inventory, there seemed to be a rope: he pulls it out and tries to throw it.

After pulling out his long rope and making several attempts to hook it onto the edge of the ledge, Henry managed to do so. Climbing up the rope, the guy crawled through the opening and found himself inside the statue's head. Under his feet, he felt a material that resembled tiles. Looking around, he sees something that looks like a sack on the opposite side of him.
