This game looks at the concept of a person's preference for being alone (introversion), or never being alone (extroversion). I know the science and exact nature of these things is not captured in the game, but the game is meant to be fun/funny too. Check out the instructions in the game menu for the skinny on controls and goals.

Controls are X (select in menu), and C, and arrows. Read the instructions for more info :)

More details, if you want them: You select your "alone" preference then play through day (office) and night (city/street) cycles. You must carefully balance your anxiety and energy levels, while striving to be understood by those around you. The more anxious you are and the less energy you have, the more likely you will be misunderstood. At the end of the day (you're understoood, or too anxious), you get to recharge in the way you like. The goal of the night cycle is to lower your anxiety and raise your energy for the next day. Failure to do this means you won't be understood, and ultimately your self worth and lonliness will increase. If your self worth goes too low, you will die. Boy did I make that sound boring. HAH :)
