Maybe the concept is too hard to grasp, although this game is terrifying by it's own. It does lack some aspects of actual horror, but puzzles aren't my specialty.
Actually, I forgot to add IMPORTANT information to the tutorial board that "Lamps in front of the woman statue are the signal of report successes" (2 Lamps = 2 report successes signal)
I prepared 8 types of jump-sacres in the game but none of those happend...
