Interesting game concept in limiting the options that the player would have to select from. The limit of options kind of straps a player in to figure out what's going on without any frame of reference.
I'm unsure what the win condition(s) were for the game along with the available options to select while playing the game, but perhaps that's part of the mystery of the game.
As stated by others and mentioned within the game, the sound was a little distracting, I wasn't sure whether it was part of the ambiance or a sound error, maybe turning it down by half should suffice for the sound. The constant static noise kind of discourages a second playthrough.
