"Why don't you come to the planetarium? The beautiful twinkling of eternity that will never fade, no matter what. All the stars in the sky are waiting for you." This intro and the impeccable opening OST, is enough to make me cry lowkey.. I'm a sucker for dystopian setting existential themes and this one got me real good 😭😭 Key never misses, absolute geniuses 🙏🙏🙏
一切本应死绝的封印都市,一个本来应该坏掉的机器人,一个活在废墟般世界里的猎人。 比起前传的1小时短篇,本篇也没长到哪里去,结尾有种戛然而止的感觉。 在绵延不绝的磅礴大雨里,生于战争的人终于见到了30年前的星空。 纵使虚假,仍旧璀璨。

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.

This short story is not a complex, sophisticated masterpiece. Indeed, it is quite predictable, uses "cheap" tricks to make you emotional, and you know pretty much everything about the characters after the first 30 minutes (although, with some notable exceptions). However, it's clear to me that none of this is the aim of this visual novel. Instead, It is laser focused on dialogue and character interactions, and I believe it greatly succeeds at this, aided by the aptly placed melancholic music. This is best exemplified by the two core scenes of this story: the "special projection", and the ending. The aforementioned strengths are put together to produce some really compelling, beautiful moments that will get you feeling [i] something [/i] , even if it isn't sadness. I thus still recommend experiencing this visual novel. 7/10

欢迎光临星象馆
我这身铁皮 就连泪水都是向上天借的
人間のエゴにより生み出されたロボット、、、ロボットに感情なんてないと理解していても、本当は悲しんでるんじゃないかって思ってしまう、そして自分勝手に悲しむのは人間だけ。
她眼窝中满溢的雨水盈眶而出,顺着双眼的眼角不断流淌。 看上去就像,在哭泣一样。 “心里面…满满的,都是幸福…”
this game felt like such a nothing burger. so much buildup for one somewhat nice moment, and then absolutely nothing interesting happening in between.
在男主眼中,她早已不是电路加零件那么简单了
