I think the game looks really good, and that it has an interesting setup. Having to string along different messages and set the settings correctly are a cool puzzle concept. The visuals are also pretty detailed, and the audio is pretty crisp as well.
My only real critique is that of the abrupt ending. It appears that the game has no actual end, and that the voice call that gives you the directions of (2, -4) don't lead to anything. This is a game jam game, so games are expected to be short and simple, but I wish there was some indicator for when the game is over. Either way, this is an interesting game concept to explore in the future if you want to.
Great job!
