You are in a virtual room with Alexa, and your goal is to find her without the use of vision. You can shout "Marco" and Alexa will respond back with "Polo". Alexa's voice will be louder if she is closer to you in the virtual room, and softer if she is further away. You can move around the virtual room by saying go "north","east","south", or "west", and say marco to check if you're closer or further to Alexa. When you run into Alexa, you win!
