I could tell before playing this that this would be a distinct game. A puzzle game in the form of a visual novel but which doesn't show any characters and the choices are comprised of pressing the buttons on the phone.
But maybe my favorite part about it is the atmosphere, how immersive it is: I was immediately drawn in by the visual effects, giving me 90's vibes, the POV, the ambience of the night, that you have to press the buttons on the phone manually. It was a pretty cool experience.
