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.

感觉尸体暖暖的
太喜欢美术和音乐了,美轮美奂,故事也很喜欢TnT
无敌的美术和一个成人童话故事。一个并不能算惊艳的故事,讨论一个老生常谈的主题:爱。 如果你不介意花10块钱玩一个小时然后感慨:成年以后才发现爱与被爱、友情与爱情确实是个成人话题的话还是推荐购入的。
