I'm not entirely sure if this game fits the theme of the sub; I just came across y'all accidentally.

This is an interesting android game that uses stereo sound to "display" a 2-d environment through which the player moves by swiping on their phone. There's nothing at all on the screen. As a sighted player, it's quite a challenge for me to focus on this method of interaction. I'd be curious what other gamers, sighted or otherwise, think of it.
