At some point, as the player makes their way through these nostalgic interactive set-pieces, the character stumbles on to a thought that they do not want to remember, resulting in a glitch-like zap which deletes it from the simulation. These happenings quickly escalate, turning into whole alternate visions and destructive actions that spiral out from each memory, paired with a abrasive digital audio-visual presentation.
The main way I make this work is by using an asymmetry of perception between the player and character. While the player sees and goes through these experiences that hint at a hidden truth, the character’s thoughts never acknowledge them, always focusing on the happy sentimental parts of each memory.
Over the course of the story, this device develops the narrative tension by emphasizing the rift between the main character’s cognition and the distorted fragments of reality seeping through the cracks.
