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.

一周目通关了he,两个人一起搬家,原来缘分早已注定。也正因如此,补其他成就发现原来存在“真的不爱”的可能性的时候好伤心。尤其是泡沫ending。 在湖边那个分支好难过。我以前觉得行动胜过口头的。但是事实上在那里果然还是选择让他知道缘由会好吧。爱要看行动,也不能当哑巴。TvT

良い良い良い!👍👍👍 彼くんのビジュアルが良くて購入 日本語翻訳はブレる部分がありつつも丁寧 ohが「おお!」「あっ…」「わぁ」と区別されていたり、一人称が僕、外向きには私と意訳されていたり 初対面の会話の辿々しさも感じられて、恋愛(を見る)ゲームの旨みがあってかなりグッと来ました 細やかなスチルと背景、立ち絵がキャラクターの奥行きを広げていて最高! 良い恋愛 良い恋愛 素敵なゲームをありがとうございます!

不知道为什么,ed的特别感谢看得我眼睛尿尿了,感觉是非常非常真诚的制作组。
I couldn't stop crying when playing it !
Коротенька новела з чудовою специфічною атмосферою. От приблизно такий самий вайб у моєї депресії Дуже стильний арт, прекрасна музика і чуттєвий сюжет. Пограла 3 години, і останню годину я просто проревіла, бо хвилювалася за гг і її кохання. Але супер пощастило, що я одразу вийшла на хорошу кінцівку, і там я вже плакала від радості. Багато досягнень в мене не відкрито, але я й не буду їх дивитися, бо я задоволена своїм хепі ендом В сумі гру рекомендую, але обережно, то там показують нутрощі((((
这个开头,挂羊头卖狗肉。以为是讨论爱是什么,比如权力、自己的投射,结果直接变恋爱故事了...?白瞎这幻想微克的设定了。恋爱故事后续也蛮潦草。
美术风格太牛逼了氛围这块很无敌 剧情比较平淡但也还不错!
[h2] 完全在照镜子以至于不停流泪的游戏 [/h2] 的确是需要对电波的游戏。因为自己和女主很像,心路历程甚至真实经历也很像,所以极其代入,对我来说是一个很棒的作品,让我重新回顾和反思了自己的人生。 只盲打了一个结局,相濡以沫,还好是它。不敢重开,不敢收集结局,感觉那样就像是要重新选择自己的人生岔路,要走上那些我无法接受的痛苦结局。 缺少爱,渴求爱,忽视已经得到的爱,不择手段获取爱,迷茫于被爱却不爱对方,恐惧于爱是否真实且长久,直到被安全地、稳稳地用爱接住,直到爱持续的时间长到我无法骗自己不相信爱。 爱不是零和博弈,是化学反应。我们既付出,又得到,在爱与被爱中,我们共同成为了化学反应后生成的新物质。
Fairly short but masterfully done first person romance visual novel with horror aesthetics. 4 Main Endings and a couple of bad endings strewn in-between. The soundtrack is a collection of very serene and beautiful instrumentals, it fits each scene very well. I am a big fan of the tracks "The Future" and "The Confession".
