How Deep Is the Dark Water? is an experimental game that imagines a cross-strait war. The player, guided by a fleeing man, slowly wanders through memories and visions constructed by the context of the war and individual experiences. At the same time, the player finds another layer of meaning of war for individuals, cultures and nations by discovering the messages hidden in each scene. From historic dwellings to steam trains carrying displaced people, from bomb shelters filled with fear and violence to burned cultural traditions, from confrontations with the ghosts of refugees under the water to the emotional orgy of social media, what is always present in this game is the back of the fleeing man who represents a helpless individual and an object that cannot be possessed or perceived clearly. As a response to the tensions in the world, this work does not directly portray war, but tries to let the player feel the separation, fear, violence and trauma of war in the process of chasing the fleeing man. Water is an important imagery in the work and is almost everywhere. The black seawater carries not only the sound of shelling, but also individual nostalgia, love, hate, and confusion. How Deep Is the Dark Water? creates an interactive scenario that allows the player to read text (or short poems) hidden in the game space, by using the right mouse button to zoom in on an object, look away, and in some cases, to see the text superimposed on the object. This technique stems from the artist’s long preoccupation and experimentation with reading texts in virtual space, and is in line with the special significance of reading in this work – the texts are the weak repercussions that lurk beneath the surface of historical events.
