It's fun, but I'm confused what the point of audio controls is if you have a visual display in front of you
EDIT: What I'm trying to say is that it feels like it takes away from the point of the game by starting you off with visuals. The fun part of this game is trying to navigate the dungeon and make it to the end by using only sound, which is awesome. The problem is that it immediately starts you off with some visuals, and most players will never turn off their moniter or close their eyes. They'll play the game like they assume it's meant to be played, by looking at the screen.
Starting the game with a black screen and allowing the player to turn on visuals if they wanted to would be a much better solution. That way, players who wanted to look under the hood could, and the general audience would learn how the game was actually intended to be played.
