Blindside is a game that relies solely on audio. You start off in the dark in your apartment after a supposed loss of power. You soon realize, however, that there are more sinister things at work. Once you realize you're now blind, strange noises begin to fill the darkness.
Relying on sound alone to make your way through the world helps make this an incredibly immersive game experience. The game provides a user interface, though it can be distracting. In a game where your character is blind, the easiest way to navigate the world is to wear headphones and close your eyes, drowning out everything apart from the sound in the game.
I personally find this game to be highly intriguing, and I would love to see it receive more exposure.
