Escape the world of red and black, and embark on a journey of struggle and salvation.

Game Genre: Biphase, developed by several college students from different universities, is a 2D platform jumping game with exploration and puzzles as its core.

Our Message: We hope that the game can show the plight of some bipolar patients in a realistic and in-depth way by depicting an "individual" in a group, in addition to popularizing the phenomenon related to the disease. We are trying to trigger the public's empathy through the individual's narrative, and call on the public to adopt a more understanding and tolerant attitude towards patients with bipolar disorder.

Abstract Narration: The narration part of this game was based on real cases around the player, mainly about the main character with bipolar disorder, who explores the abstract world of red and black mental images to find an exit.

Puzzle Levels: The level process is a metaphor for the condition "bipolar disorder". The main components of the scene, red and black, fade into the background of the same color, just as people wrapped in extreme emotions often fail to perceive the whole picture. The red and black worlds in the game refer to the "manic" and "depressive" mood poles of bipolar disorder, and the characters are in a world divided by two levels of emotions.

How to Play: In the level, players manipulate the main character to move left and right, jump, press the switch, jump to change the background color. Players switch back and forth in the red and black dual-phase mental image world, and interact with the scene components with different states of passage in the two colors of the background, when the scene components and the background color is the same, the components are in non-interactive state; when the scene components and the background color is opposite, the components are interactive state. Players gradually explore the path to the end in the switching of red and black.

Great conecpt!

This game is great, and I love the history behind it. Will you be making more levels?

Edit: I found a glitch. At the end of the first part, you have to exit and re enter to get to the second part. Please fix this if you can, but if not, it doesn’t matter

How this app found its way onto my device after a fully wiping phone through iTunes w/only default stock and bloat apps. It also has an email address which is not mine that is allowing forwarding. Please explain. Not going to rate because I do not and have not used the app personally. To be fair.

Hi, we opened the pre-order feature before releasing. Please check your pre-order history in App Store or on Apple's website to check if anyone that used your phone before that have pre-ordered Biphase.
Please note, Bihpase is a totally free game with no ads. So it won't bring any loss to you. And Biphase is not able to install itself on your device.
