As ordinary people we all strive to find true happiness in life. But no... not like this.... something is REALLY off about this... This game serves to remind us that life is much more complicated than finding true happiness. Sadness, struggle, and anger are a part of the human experience. If your only emotion is happiness... then.. are you really human?
