Evaluation
Biphase is a free-to-play 2D puzzle platformer released on March 29, 2021 by a small team of college students. The store description presents it as a complete, self-contained experience with a defined narrative and puzzle set — there is no mention of planned expansions, DLC, seasonal content, or any future additions. After launch, the developer issued one patch on April 15, 2021 (fixing save logic and a language bug) and added a Polish language translation on July 14, 2021. Those are the last recorded communications from the developer — both from 2021. No further posts, updates, roadmaps, or announcements have been made since July 14, 2021. The game has no DLC listed, no outstanding commitments, and no signals of any planned future content. Given the nature of the project — a student-made indie game built around a specific creative message — it was almost certainly launched as a finished product, and the post-launch activity confirms only minor polish work before the team moved on.

About this game
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 the 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 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.
Special Thanks: DBSA. The Depression and Bipolar Support Alliance (DBSA), is a nonprofit organization providing support groups for people who live with depression or bipolar disorder as well as their friends and family.
