People with apeirophobia really shouldn’t watch this.
Everything has been recorded at first-person perspective. It resulted in infinite psychedelic visuals such as giant spirals, never-ending walls, and gigantic perpetual portal rooms. Scary at first when you’re face to face with yourself. Such visuals potentially can trigger anxiety about mirrors and stairs to some people. There is no way to get out without restarting or using cvars. Chell doesn’t die by doing this, and it looks like there’s no gravity anymore.
