We’re creating a video game with no graphics, played entirely using audio. It is an audio adventure, set in a fully 3D world that you’ll never see.
It's called BlindSide, and it’s one of the first games to bring a brand new gaming experience to sighted players, that can also be fully enjoyed by visually impaired gamers. So far we’ve completed 10 minutes of gameplay to prove out the technology, and demonstrate that our core mechanic is fun. There have been a handful of audio-only games, but nothing like this before.
