Biphase is a 2D platform jumping game with an emphasis on exploration and puzzles. In the game, the player takes on the role of a bipolar character who is attempting to discover and breakthrough their own identity in an abstract red and black landscape. The game's protagonist is a young girl who must overcome changes in her environment in order to reach the exit that will bring her to the following track. This is a lovely metaphorical approach to bipolar disorder since it depicts the difficulties of moving in a constantly changing environment, which is something that people with bipolar disorder confront in their daily life owing to mood swings caused by the disease. Nonetheless, the game sends a positive message; while the girl may find it more difficult than the others to "journey" in his own life, reconciling with the disease's facts enables her to tackle any problem with courage.
