About Biphase

✦ AI summary

Biphase is a 2D platformer where you navigate abstract red and black worlds that represent the manic and depressive states of bipolar disorder, solving puzzles by switching between emotional phases to interact with environmental elements. Created by college students in collaboration with mental health advocates, the game uses gameplay mechanics as metaphor to foster empathy and understanding for those living with bipolar disorder.

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.

✦ AI summary

Biphase is a minimalist puzzle game centered around switching between two phases of worlds to solve increasingly challenging brain-teasing puzzles. Players praise the intuitive controls, distinctive visual style, clever mechanics that reward patience and attention to detail, and atmospheric soundtrack, with most finding the puzzles engaging once the core concept clicks.

Игра Biphase - это оригинальная головоломка, основанная на необычной механике смены фаз, переворачивающей мир с ног на голову. Визуально игра достаточно минималистична, но стильная, с приятной цветовой палитрой. Главная фишка - это необходимость манипулировать двумя разными мирами, переключаясь между ними, чтобы решить головоломки. Изначально задачки кажутся простыми, но сложность постепенно нарастает, заставляя серьезно попотеть над поиском решения. Управление интуитивно понятное, а вот понимание логики игры приходит с опытом. Иногда даже небольшое изменение перспективы оказывает огромное влияние на прохождение уровня. Это игра, которая требует терпения и внимательности к деталям. Саундтрек ненавязчивый и хорошо дополняет атмосферу. Из минусов могу отметить, что иногда сложность головоломок кажется немного несбалансированной. Бывают уровни, которые проходишь с первого раза, а над другими приходится сидеть часами. В целом, "Biphase" - отличный выбор для любителей нестандартных головоломок, которые не боятся бросить вызов своему интеллекту. Рекомендую!

Nice puzzle game. It took a little while for the mechanics to click, but the puzzles flowed really well and were fun to solve after that. I loved the visual style, too.

the puzzles are needlessly frustrating to deal with for no reward. basically, I'm not going to waste my time trying to beat the game because (1) it isn't fun and (2) there isn't even an achievement for beating the game.

CW: Bipolar disorder and mental illness. [h1] ▶️ Gameplay [/h1] https://www.youtube.com/watch?v=6xismQAmAeY [h1] 👍 Pros [/h1] + Beautiful minimalist graphics with intentional color scheme + Fun mindboggling puzzles + Simple presentation but deeply emotional gameplay + Endearing character + Mechanics that makes sense (e.g. doom scrolling will lower your energy bar) + Amazing music [h1] ❗Cons [/h1] - Some stages were quite challenging to complete/navigate (but I think that is the point of the game) [h1] 🤔 Conclusion [/h1] This game is a hard to play... not because the puzzles are difficult to solve, but because they symbolize experiences of someone with Bipolar Disorder, a mental health condition that causes extreme mood swings of emotional highs (mania) and lows (depression). Thought-provoking and packaged in a cute, minimalist way, this is an amazing visual experience through the minds and eyes of people who struggle with this, and I really appreciate the narration/explanation at the end. I can't believe it's free. Highly recommended! ˚　　　　✦　　　.　　. 　 ˚　.　　　　　 . ✦　　　 　˚　　　　 . ★⋆. 　　　.   　　˚　✭　 　　*　　 　　✦　　　.　　.　　　✦　˚ 　　　　 ˚　.˚　　　　　✭　.　　. 　 ˚　.　　　　 　　 　　　　 ✦ ⸜(˶ᵔ ᵕ ᵔ˶ …

This is such a neat platformer and I'm glad I got to play it. Short and sweet. Thank you for making such a great simple, but challenging game!

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
