This game has a very good game atmosphere, the overall difficulty of decryption is very high, but the excellent graphics and the creepy background music give the whole game a lot of points, plus you are trapped in a cabin, the whole cabin Only you alone adds to the atmosphere of the secret room. Although the overall environment of the game is brighter, because the whole is a secret room, you can't speak. There is no language in the game, which makes the atmosphere of the whole game extremely depressing.
The entire secret room is not very divided into upper and lower levels but there are many puzzles and objects to be solved. There are many things hidden in a small wooden house. The core of the whole thing revolves around getting out of the book world.
