Prices
The United States storefront in every case, so this compares stores and not countries.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Aug 27 → 0.71/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Romantic, fantastical, and eerie, Zero-Sum Heart is a coming-of-age story about love.

Enter a magical boarding school on our protagonist's eighteenth birthday as she makes a monumental decision and derails her life.
A ritual sacrifice got her everything she ever wanted: an adoring crowd (faceless), a newfound power (dangerous), and a whirlwind romance (one-sided). But without a heart in her chest, how could she love anyone back? Does she even need to?

A short 2-hour story with multiple endings, blending genres of romance, teen drama, thriller/horror, and magical realism.
Vibrant and psychedelic hand-drawn illustrations that blur the lines between reality and fantasy.
A witchy, sinister, and groovy original soundtrack.

Zero-Sum Heart contains visual depictions of self-mutilation, violence, and gore, although not particularly graphic due to the non-realistic art style.
The story also contains limited depictions of stalking, harrassment, abuse, toxic familial and romantic relationships, murder, and suicide. Please note that due to the premise of the story, any romantic interaction the protagonist initiates with characters under the influence of magic might involve dubious consent.
If any of the above might be triggering for you, caution is advised while playing the game.

刚打完一个结局,非常美丽的故事和美术……可惜在工位电脑玩的无法体验音乐,很期待其他结局!
流程很短的青春伤痛文学小品()但是和解结局比较美味,美术与感情线也萌。选项美术做得别出心裁,但是请注意steamdeck上游玩得触屏辅助喔(总体而言sd食用OK)
非常棒的游戏。内容很细腻。优美的爱情故事。感觉作者是infp小蝴蝶。很适合绿人玩的游戏,像一部动画电影。

打折的时候买的,画风很喜欢,故事还算有意思,只是再打磨一下就好了,有部分感觉太沉浸于絮絮叨叨自我感受,情感的转换铺垫不足,留白太多。
第一次就HE了我简直是天才
盲打还是太权威了
两颗太阳苦累地落下,一个在空中,另一个在我胸膛里。哪一颗太阳更温暖,哪一颗会更快变冷。两颗太阳结了冰,那燃烧最炽烈的一个,将最先去死。我的良心怎能忘记这两个太阳?我怎能接受这日益冷落的苦痛? 一颗心在燃烧。热浪将我和世界分隔两地。如今大雪将至,我从持续数年的灼烧中醒来,眼前一片纯白与明朗,有如泡沫缠上我的伤痕,我靠近看,那是一万颗心在闪耀。
agreed with one comment which says that the amount of attention on the male lead is a little devastating. although, overall game is well-written, art is unique and pleasing, music isn't bad too. i think that it's an amazing project for a small indie studio, so wish all the luck for the next project
女巫姐姐实在是非常之好看! 我可能是反应比较迟钝,看了后记才把这个故事和海的女儿联系在一起,于是意识到男主设计成长发还绑个缎带原来是cos中世纪王子啊,设计成文艺长发男还挺合适。可能是因为内在和原作王子没半毛钱关系所以外表需要像一些? 因为男主形象过于理想化所以BE的条件稍微有点苛刻了。 首饰那一段设计得很好我特别喜欢! 小美人鱼也许并不是为王子化为泡影的,她是为自己对未知世界的幻想与憧憬和爱化为泡影的,也许她反而是懂得什么是爱的那一个。
其实刚开始关注这个游戏 是因为画风 完成游戏 却被文案深深吸引 爱 真的是人类历史中最复杂 而又最伟大的命题
